Mila Kunis was on '7th Heaven' Plus 16 Other Guest Stars You Forgot About

'Tis the season of disbanded casts reuniting and snapping photos for social media in an effort to make the world simultaneously implode. We've seen it with Mean Girls, The Little Rascals, and more, and now it's your favorite 7th Heaven family's turn. The Camdens — Reverend Eric, Annie, Matt, Mary, Simon and Lucy — got together to show us that there's no greater feeling than the love of a family. (And yes, Ruthie was inexplicably missing).

Nevertheless, all this nostalgia had us remembering some of our favorite episodes and guest stars from the series. Many of whom have grown-up and gone on to be successful Hollywood actors. So without further ado, here are 17 actors you probably don't remember from the WB's (remember that?) 7th Heaven.

Mila Kunis

Aww, look at that mug! Mila Kunis played Ashley, a friend of Lucy’s who caused a bit of drama at the Camden house when she found out her crush didn’t have likewise feelings.

You can catch her in “Saturday” and “With a Little Help from My Friends”.

Alan Thicke

Before Robin Thicke had dropped “Blurred Lines” or dropped drugs (that we know of), his dad appeared in an episode of 7th Heaven playing the father of dreamy Robbie Palmer.

You can catch him in, “Parents”.

Tyler Hoechlin

Before he was half wolf on MTV’s Teen Wolf, Hoechlin played a love interest for more than one of the Camden girls. He appeared in

Alison Lohman

The film actor once appeared on the family-friendly show as a woman who was pregnant out of wed-lock! Scandalous, indeed. You can catch her character, Barbara, in “Let’s Talk About Sex”.

Ashlee Simpson

Ashlee Simpson, who played a love interest for Simon as Cecilia Smith, appeared in 39 episodes with her bleached-blonde ‘do and down-home values.

Mary Kate & Ashley Olsen

Sue and Carol Murphy were on one episode of 7th Heaven in “Gossip”. I realize Mary Kate and Ashley are two separate individuals, but pairing them together only seems fair. They appear in nearly matching ensembles, after all!

Gabrielle Union

Keesha Hamilton was a friend of Mary’s at school. Played by Gabrielle Union in five episodes, we’ll never forget those denim overalls.

Geoff Stults

Enlisted’s Geoff Stults played Ben Kinkirk and was a police officer with a good heart on 7th Heaven. He appeared in 23 episodes as the borther-in-law to Lucy Camden.

Kaley Cuoco

She played Lynn, and appeared in an episode entitled ”Relationships.”

Kyle Richards

The Real Housewives of Beverly Hills’ star was on 7th Heaven, and she played

Leighton Meester

In two episodes, Meester played Kendall, sporting a look very similar to her Gossip Girl character.

Lance Bass

Oh yes, Lance Bass was on 7th Heaven as Rick Palmer, playing the frosted-tips-wearing love interest of Lucy. They even had a steamy make-out scene.

Matt Czuchry

Before he was Ivy-league Logan on Gilmore Girls, he was on 7th Heaven playing Carl in “A Cry for Help.”

Ashley Tisdale

“Breaking Up is Hard To Do” is the episode where you’ll catch a brunette and curly-headed Ashely Tisdale vying for the affections of pint-sized Simon. D’aww.

Katie Cassidy

Arrow’s Katie Cassidy was in four episodes of 7th Heaven and played Zoe, a troubled teen (weren’t they all?)
