The Hills may have launched its young stars to TV fame, but they weren't the only famous faces to appear on the iconic reality series. There were plenty of celebrity cameos on The Hills throughout its six-season run — including some that, all of these years later, you may have forgotten about. Or didn't even register the first time around.
Often, celebs popped up because of the cast members' jobs: Lauren Conrad and Whitney Port worked at
Teen Vogue for many seasons, Heidi Montag did PR with Brent Bolthouse, and Audrina Patridge worked for Epic Records. As The Hills went on, the stars became celebrities themselves, attending events as invited guests instead of working them. Sometimes, it was easy to blink and miss a famous person walking by on a red carpet. Other times, a star was a part of the plot line during the cast members' work tasks.
Lauren and Whitney helped Lady Gaga with a wardrobe malfunction when she was still an up-and-coming artist; Kim Kardashian chatted with her then-stepbrother Brody Jenner at Heidi and Spencer Pratt's housewarming party;
Vanderpump Rules star Tom Sandoval showed up for a Teen Vogue swimsuit casting when he was still an unknown model trying to make it in Los Angeles, and his costar Scheana Marie appeared in multiple episodes during show's fifth season as a friend of Stacie Hall's, aka Stacie the bartender.
In honor of
The Hills: New Beginnings revival, let's revisit all of these star-powered moments.
Paris Hilton — Season 1, Episode 1
Nicole Richie — Season 1, Episode 1
Jonathan Bennett — Season 1, Episode 1
Landon Clements — Season 1, Episode 3
Before she became a cast member on
Southern Charm, Landon Clemonts worked at Bolthouse Productions with Heidi as "Brent's other assistant," and she was totally fine taking a back seat on the show. In 2016, the told Southern Charm alum Page Six, "I wasn't on the show that much because, at the time, I really wanted to build my career."
Aside from that, she claimed, "They wanted me to go after so-and-so’s boyfriend and all this. That's not me." But whose boyfriend though?
Anna Wintour — Season 1, Episode 3
Lauren hopped on a red eye flight from Los Angeles to New York City so she could deliver a dress to her boss Lisa Love for the Marc by Marc Jacobs fashion show. As a new intern, she didn't get any perks, like staying for the actual show, but
was sitting in the front row. With sunglasses on indoors. What. A. Legend. Vogue editor Anna Wintour
Tom Sandoval — Season 1, Episode 8
Lauren and Whitney were in charge of casting guys their age for a swimwear photoshoot in
Teen Vogue. One of the men at the casting was Tom Sandoval, who of course now stars on another legendary reality show: Vanderpump Rules.
Eva Marcille — Season 2, Episode 2
It was a stressful situation when Lauren and Whitney worked the Ashley Paige fashion show. However, everyone else in attendance had fun, including
America's Next Top Model winner and current Real Housewives of Atlanta cast member Eva Marcille, who was among the guests.
André Leon Talley — Season 2, Episode 11
This episode blessed
The Hills fans with one of the most historic moments in the show's history: Whitney falling down the stairs during a live segment on Good Morning America. André Leon Talley, the former editor-at-large for Vogue, is the one who decided that Whitney was model material. As complimentary as that is, Whitney probably wishes he never asked her to model dresses on live television.
Marc Jacobs — Season 3, Episode 12
Teen Vogue assignment in New York, Lauren was asked to help at Marc Jacobs, since he was her favorite designer. To her surprise, the man behind the brand showed up and introduced himself while she was alphabetizing inventory. Oh, the glamour.
Emmy Rosum — Season 3, Episode 13
The Hills started out with Teen Vogue's Young Hollywood Party and continued the tradition throughout the series. During Season 3, the party was off to such a fashionably late start that even Emmy Rosum was in the crowd waiting to get inside.
Hayden Panettiere — Season 3, Episode 13
At least Emmy Rosum wasn't the only one stuck in a line. Hayden Panettiere was in the same predicament at the Young Hollywood Party.
Selena Gomez — Season 3, Episode 13
This super close-up moment is of a baby-faced Selena Gomez. Yes, she had a blue streak in her hair, but it was 2007. Give her a break.
Hilary Duff — Season 3, Episode 13
After all of the logistical problems at the Young Hollywood Party got sorted out, they were waiting on one thing: Hilary Duff's arrival. As soon she showed up and got seated, the fashion show began.
Justin Timberlake — Season 3, Episode 14
There was a lot of drama at the Declare Yourself party. Heidi and Lauren were both "coincidentally" invited by their bosses to attend, which was extremely awkward, and the understandable focus of the episode. However, eagle-eyed viewers spotted Justin Timberlake walking into that same event. If only he chimed in on the Lauren vs. Heidi tension.
Sean Kingston — Season 3, Episode 14
When Audrina worked at Epic Records, she spent the day with Sean Kingston, an artist signed to the label, while he rehearsed, did a soundtrack, and ultimately performed on
Jimmy Kimmel Live!
Lady Gaga — Season 4, Episode 5
Whitney styled then-budding artist Lady Gaga for a big performance. However, the singer's zipper got stuck and she was in a panic. That's when Lauren stepped in and saved the day. Yes, Lauren actually got to assist Lady Gaga with a wardrobe malfunction, and in return, Gaga called her her hero.
Taylor Armstrong — Season 4, Episode 7
Stephanie Pratt went on a secret date with Lauren's former flame Doug Reinhart. Well, as secret as a filmed interaction can be. However, Brody's mom Linda Thompson spotted them and came over to say hi. She was out with her good friend and
Real Housewives of Beverly Hills OG Taylor Armstrong.
Brandy — Season 4, Episode 12
Brandy consulted Audrina and her coworker Chiara Kramer on which photo she should use for an album cover while they were at the recording studio. Unfortunately, Brandy did not return the favor and weigh in on Audrina's ups and downs with Justin Bobby Brescia.
Scheana Marie — Season 5, Episode 3
During Season 5, Spencer spent a lot of time with Stacie the bartender and her friends. He asked them what song it would take to get them dancing on the bar and Scheana responded with Def Leppard's "Pour Some Sugar On Me," but the bar-top dancing did not actually happen.
White Tie Affair — Season 5, Episode 8
The White Tie Affair went out with Audrina and Stephanie for a night out. After a lot of flirting, the bassist revealed to Stephanie that he has a live-in girlfriend back home, and she didn't waste any time getting out of there.
Tom Green — Season 5, Episode 14
There's no storyline to this one. Tom Green just happened to be at one of Heidi's work events.
Ryan Cabrera — Season 6, Episode 2
Singer Ryan Cabrera briefly dated Audrina and appeared during several Season 6 episodes. It all came to head when Audrina started crying and left one of his concerts... and went back to Justin Bobby, of course.
Amber Rose — Season 6, Episode 8
Another season, another Young Hollywood Party. This time
Nylon hosted the event, which meant the cast members got to attend as guests instead of employees along side Kanye West-era Amber Rose, futuristic shades and all.
Shenae Grimes — Season 6, Episode 8
90210 cast member Shenae Grimes attended Nylon's Young Hollywood Party along with the cast members.
Kim Kardashian — 'The Hills' 10th Anniversary Special
This scene went down while the cast filmed Season 3, but it did not make the cut. Kim Kardashian attended Heidi and Spencer's housewarming party along with
(ex?)-stepbrother Brody Jenner. This did not make it into the show's original run, but it was a part of the unaired footage during The Hills 10-Year Anniversary Special, which aired in 2016. Just imagine if Kim was a part of The Hills. That really would have changed the reality TV landscape.
There was plenty of drama on
The Hills to keep fans entertained, but wondering which famous faces might pop up in the next scene was always such an exciting part of watching. Now, the show's stars are celebrities in their on right, but back then, viewers tracked the celeb cameo appearances just as much as Spencer's changing facial hair.
