Oftentimes when celebrities' romantic relationships head south, they take one of three approaches. They either refuse to discuss the details surrounding the fallout (regardless of how vocal they were about the relationship in the beginning), deny it until they have no choice but to 'fess up and release a vaguely worded public statement, or they take the creative route, choosing to show us how truly artistic they are by letting it all hang out in the form a "diss my ex" song.From Carrie Underwood's "Before He Cheats" to Kelis' "Caught Out There," there's no secret that despite however fabulous they may appear to the untrained eye, celebrity breakups can get just as ugly as anyone else's. As a result, some of Hollywood's finest have practically written the blueprint on how to garner mass success by singing about an ex. The latest to join the "I hate you so much right now!" bandwagon is rapper Nelly, whose new track "Thanks to My Ex" is believed to be inspired by his recent tiff with boxer Floyd Mayweather and contains a few subtle digs at his former girlfriend, singer Ashanti. Here's a list of nine other celebrities whose relationship woes have wound up on wax. Taylor Swift "Dear John"
I have a feeling that Taylor Swift's high school probably voted her "Most Likely To Diss An Ex in a Song." There's no secret that for "Dear John," the guy in question is John Mayer, who claims the song humiliated him.
Kanye West "Blame Game"
This track set off a war of words between West and his ex, the formerly elusive Amber Rose, who was initially tight-lipped regarding the couple's breakup. Aside from a few nasty public exchanges, the song also resulted in West coining the infamous line "Yeezy taught me."
Ray J "I Hit it First"
Seriously, Ray J who cares if you hit it first? This song should serve as a huge stop sign for any girl who suffers a temporary loss of sanity and considers dating him.
Justin Timberlake "Cry Me a River"
Apologies in advance for drudging up the hurt from the past for all those people who thought Justin Timberlake and Britney Spears were the couple who would last. Unlike Timberlake, please don't cry me a river.
P!nk "So What"
The cool thing about this song is that even though P!nk dissed her husband Carey Hart, he appeared in the video and they wound up reconciling.
"You Oughta Know" Alanis Morrissette
In one of the angriest songs ever written, Alanis Morrissette ranted and raved about the grave injustices doled out by her ex. The lyrics produced even further heartbreak when the public realized the ex in question was Dave Coulier, better known as "Uncle Joey" from Full House.Chris Brown "Theraflu" remix
All I have to say about this one is...the nerve of Chris Brown. He claims he wasn't referring to his ex Rihanna, but the Twitter fallout that occurred after the fact indicates that we're not the only ones who thought his explanation was cough*bullshit*cough.Bon Jovi "You Give Love a Bad Name"
The title says it all. This song became one of Bon Jovi's top hits, proving that creatives often produce masterpieces from their misery. And the woman who gave love such a bad name? Sweet-faced actress Diane Lane.Ed Sheeran "Don't"
Sheeran's on track to become the female Taylor Swift. Not only did he admit to dissing his ex singer Ellie Goulding on the track "Don't," he recently followed it up with another musical smackdown.
