Oooooh, lord. Teen Mom star Farrah Abaham wanted to be a singer, and released some absolutely horrible songs to no avail (but great amusement). She's also a terrible actress, as evidenced by her attempts to convince us her sex tape was released by mistake. Screaming is a different story, as she proved with James Deen ...
Kristin Cavallari found her calling when she became a mom and started designing clothes. Now we don't have to talk about her direct-to-DVD Van Wilder installment.
The Bachelor, Jake Pavelka, thought he would use his time on ABC's reality love show to launch an acting career. He's shown up in several episodes of The Bold and the Beautiful. And that's it.
Tila Tequila really, really wanted to be a singer. But, well, her song was called "I F*** The DJ." So then she made a sex tape.
After The Hills ended, Audrina Patridge had small parts in two movies. Then her acting career ended so she took her clothes off for Maxim to stay semi-relevant.
Once upon a time, Real Housewife of Atlanta Kim Zolciak-Biermann thought she'd be a singer. Bahahahahah. She found her calling as a reality TV-making machine.
Kim Kardashian tried to break into serious acting with a role in a Tyler Perry film but settled on acting (like herself?) in her family's reality TV empire instead.
Arguably the most successful actor on this list, Stephen Colletti (The Hills) played virgin skateboarder turned bartender for 52 straight episodes on One Tree Hill. And then he did pretty much nothing else. Bummer.
Oh, Heidi Montag. The Hills star once said she wanted to be Britney Spears. That...didn't happen. And then she made herself completely unrecognizable thanks to plastic surgery addiction.
Kevin Federline had a three episode arc on One Tree Hill in 2008 and then he went back to being a baby daddy. He now has, what, 6 kids? 7? With three different women. THAT WE KNOW OF.
Paris Hilton's biggest claim to acting fame is being paid to walk the red carpet at places like Cannes and the Oscars.
Mike The Situation Sorrentino
Mike "The Situation" Sorrentino hoped his stint as a meathead on The Jersey Shore would help him launch a rap career. Instead it sent him to rehab.
Ali Lohan wanted to be an actress like her big sister. Then she wanted to be a recording artist. Now she's a sort-of model.
Like The Situation, Angelina Pivarnick dreamed of a career in music. 2010's "I'm Hot" made sure that would never happen.
The Real Housewives of New Jersey star Melissa Gorga has released at least 5 singles, none of which you've probably heard.
