10. Tila Tequila
The bisexual star didn't exactly get her notoriety from reality shows per se, but gaining attention for being a MySpace personality is practically the same thing. She then increased her presence in the world by landing her own reality dating show, A Shot at Love, where she looked for the right man or woman for two seasons. Since then, she hasn't done another show, but she's continued using the internet (and the tabloids) to extend her 15 minutes with lots of salacious, and sometimes tragic, stories.

9. Dave Amerman
You might not recognize the name because he's better known to the world as 12 Pack, a nickname that he got from New York (not the city) on I Love New York after he showed off his toned stomach muscles. He didn't find love there, so he went after cold-hard cash on I Love Money and then tried again to find love (or more likely fame) on Daisy of Love, where he did everything, including donning a Speedo, in order to stay on TV

8. Dr. Will Kirby
Most true famewhoring reality stars go on TV because they have no discernible skills, but that's not the case at all with Dr. Will. He's a licensed medical professional who practices the lucrative specialty of dermatology. He took some time off to spend a summer being devilishly manipulative in the Big Brother house and then again for Big Brother: All Stars. Out of the deal he got a gig on the docudrama Dr. 90210 and met his friend-turned-business partner Mike "Boogie" Malin (who is another famewhore, albeit less educated than Dr. Will) and they both appeared on the competition show Battle of the Network Reality Stars. Who knows where he'll show his mug again, but it will likely be a stunt to further promote a business venture or his practice.

7. Theo Von
Theo Vonkurnatowski, who joined the cast of Road Rules and then shortened his name, did Real World/Road Rules Challenge for a few seasons and Battle of the Network Reality Stars before he tried his hand at stand-up comedy by auditioning for Last Comic Standing. He was relegated to a web tie-in series, which is only a slight step up from Daniel Franco's Idol audition. He also participated in the cheesy comedic parody show Reality Bites Back. When will these reality stars learn not to bite the hand that feeds them?

6. Trishelle Cannatella
Reportedly, Trishelle was originally auditioning for another reality show when she was plucked to be on The Real World: Las Vegas. For a hot blonde with a desire to be famous at all costs, she certainly made the most of her RW stint by participating in a three-way in a hot tub, which has since become become practically legendary. Since then she's done the obligatory stints on Real World/Road Rules challenge and also participated in Fear Factor, The Surreal Life, Kill Reality (a series about making a horror reality parody), Hulk Hogan's Celebrity Championship Wrestling and in the always classy Lingerie Bowl.

5. Jon "Jonny Fairplay" Dalton
While we're still quite shocked that this notorious Survivor pathological liar didn't make it on to the forthcoming Survivor: Heroes vs. Villains, he's really had more than his fair share of reality appearances. In fact, after his lie about his grandma dying on Survivor, he did the All Stars season, Celebrity Bull Riding Challenge, Fear Factor, Kill Reality and even went into professional wrestling for a bit to stay in the spotlight. Topping all that, he procreated with yet another reality star (Michelle from Season 4 Top Model), possibly creating an entire new generation of reality TV wannabes.

4. Megan Hauserman
What's a Playboy model to do when she's attractive, has fake ginormous boobs and can't get a job on The Girls Next Door? Go on Beauty and the Geek and show off her lack of education, for starters. Then desperately try and date Bret Michaels, until he figures out she's more interested in the cameras than him. Then take her little pocket-sized dog and go on I Love Money and Charm School and be so horrible that VH1 grants her a self-titled series, Megan Wants a Millionaire. Things didn't turn out so well with that last gig, though, so hopefully that means we're free of Megan... at least for a while.

3. Omarosa
Another one of reality TV's worst people, she took The Apprentice from a show about business to a show about backstabbing, screaming and complaining. To her credit (we suppose), this landed her a return appearance on Celebrity Apprentice, a spot on The Surreal Life and a gig on Battle of the Network Stars, not to mention the added attention she gets from just saying ridiculous things to the media whenever she's given the opportunity. To make matters worse, there are rumors that Trump is trying to help her get her own dating show. Just what the world doesn't need.

2. Speidi
Spencer Pratt and Heidi Montag may have only had time in their very busy lives to appear on The Hills and I'm a Celebrity... Get Me Out of Here (and Heidi did a handful of small appearances on Laguna Beach), but to us, it feels like they've been inescapable. They do many desperate things in order to get more reality screen time, like staging fake weddings, trying to launch a music career and indulging in extreme plastic surgery. It seems highly unlikely that these two will ever do anything that doesn't involve the tabloids and reality television in some way, shape or form, which means we may be stuck with them for years to come.

1. Rob Mariano
Boston Rob was an aggressive Survivor player, and we thought (hoped) he had fallen off the planet after his first season on the show, but then he made a comeback with Survivor: All-Stars. That's where he met his fellow partner in reality crime Amber, and together they earned an annoying nickname (Romber), had their proposal and wedding televised, competed in The Amazing Race and starred in a show about him trying to become a professional poker player (Rob & Amber: Against the Odds). Now he's back in Survivor: Heroes vs. Villains for yet another shot at reality TV glory, but, thankfully, his wife is not participating this time.

Honorable Mentions:
Even though she's been out of the limelight for a bit, Adrianne Curry deserves some sort of lifetime achievement award for not only parlaying her Top Model win into a Surreal Life stint, but also for snagging herself a Brady kid and another reality gig out of the deal.

Also, Stephen Baldwin is probably one of the biggest reality famewhores on the planet, but we left him off the list because he mostly got his start outside the genre by acting in some (somewhat) credible scripted films. But since then, he's done Celebrity Big Brother UK , I'm a Celebrity... Get Me Out Here, Celebrity Apprentice, Celebrity Bull Riding, The Mole and Fear Factor. So if you've got a new reality show and need a celeb, call him. He's unlikely to turn you down.
