10. Jake Pavelka (The Bachelor, season 14; Bachelor Pad, season 2)
Bad Boy Move: We were rooting for Jake to win Jillian's heart, especially after he came back to try to warn her about Wes. On his own season of The Bachelor he was the picture-perfect guy. But after the post-split TV interview with Vienna, we were left with the feeling that Jake loved the spotlight more than anything else. It wasn't at all surprising when his fellow Bachelor Pad contestants couldn't wait to get him out of the house.

9. Vienna Girardi (The Bachelor, season 14 — Jake; Bachelor Pad, season 2)
Bad Girl Move: This self-proclaimed spoiled daddy's girl didn't make many friends in the house, especially after she decided all the other girls were fake. In the end, Vienna was left standing with the final rose and an engagement to Jake. Their bitter, highly publicized split earned her a smidgen of our sympathy. Her teary stint on Bachelor Pad with boyfriend Kasey Kahl didn't redeem her.

8. Michelle Money (The Bachelor, season 15 — Brad; Bachelor Pad, season 2)
Bad Girl Move: The hair stylist was laughably funny in her self-centered and arrogant confessionals. She wasn't above catty behavior and using feminine wiles to pull Brad away from the other girls. Thanks to a mysterious black eye, she also came off as a touch crazy.

7. David Good (The Bachelorette, season 5 — Jillian; Bachelor Pad, season 1)
Bad Boy Move: He didn't have a girlfriend back home or bad-mouth bachelorette Jillian behind her back but no other man has so heatedly championed the Man Code. The trucking contractor unleashed the code on fellow contestant Juan Barbieri when he faked drinking a shot just to fit in with the other guys. In fact, it made Good want to ''beat the s--- out of him.'' Luckily, Good used his chance at a do-over on Bachelor Pad to show us his mellow side. He won and used his cash prize to write a book about — what else? — The Man Code.

6. Courtney Robertson (The Bachelor, season 16 — Ben)
Bad Girl Move: Courtney Robertson may have wormed her way into Bachelor Ben Flajnik's heart but to the rest of America she was that season's girl who fans love to hate. Between frequent Charlie Sheen references and secret skinny-dipping dates, it was hard to believe the model wasn't there just to play the game. When the fiancés showed up teary and barely-hanging-on during season 16's After the Final Rose special, haters were validated. Courtney and Ben called it quits shortly thereafter.

5. Tierra LiCausi (The Bachelor, season 17 — Sean)
Bad Girl Move: You don't get labeled a ''Tierra-rist'' without pulling some shenanigans. The minuscule manipulator was chronically injured during her stint on the show, and she wasted no opportunity to milk her supposed brushes with death for sympathy from Sean. For a while, it seemed like the resentment of the other ''ladies'' only drew her closer to her ''husband,'' but Tierra ultimately went down in a grand Jekyll-and-Hyde-esque meltdown in which she accused the bachelorettes of trying to steal her ''sparkle'' and uttered the insta-catchphrse, ''I CANNOT CONTROL MY EYEBROW!'' Thus ended the war on Tierra.

4. Rozlyn Papa (The Bachelor, season 14 — Jake)
Bad Girl Move: Just weeks into wooing Jake, Papa cozied up to a Bachelor producer off screen. The ''inappropriate relationship'' got her kicked off the show. We'll probably never know the whole story of one of biggest Bachelor scandals but Papa's cold ''I don't think that my personal life is really anybody's business'' explanation probably didn't help her case.

3. Wes Hayden (The Bachelorette, season 5 — Jillian; Bachelor Pad, season 1)
Bad Boy Move: This country crooner lost us the minute he pulled out that ever-present guitar. He really lost us the first time he sang ''Love, It Don't Come Easy.'' Over and over again. It wasn't hard to see he was on the show to promote his music career, unless you were Jillian, who kept him around for way too long. When he was finally eliminated, Wes cemented his villain status as he announced in the limo that he was the first guy to make it to the final four...with a girlfriend back home.

2. Justin ''Rated R'' Rego, (The Bachelorette, season 6 — Ali; Bachelor Pad, season 2)
Bad Boy Move: Justin ''Rated R'' Rego unbuttoned his shirt on the first night to reveal a wresting shirt emblazoned with ''Rated R''. He went on to court Ali, while keeping in touch with not one but two girlfriends back home in Canada. He eventually hobbled to his exit from the show after Ali confronted him, leaving a bad-boy reputation in his wake. By the time he entered the Bachelor Pad house in season 2, he had fully embraced his image.

1. Bentley Williams (The Bachelorette, season 7 — Ashley)
Bad Boy Move: Ashley fell hard for this single dad from Utah. Too bad Bentley wasn't interested or even attracted to Ashley, who he dubbed an ''ugly duckling.'' Instead he spent his on-screen time toying with the Bachelorette's emotions and used his confessionals to share gems like he'd ''rather swim in pee'' than plan a wedding with her.
