1. Rachel Uchitel

Tiger’s #1 on-the-side girl has made herself a household name. And has reportedly kept the sordid details of their affair quiet for the golfer, to the tune of $10 million dollars in hush money.

2. Ashley Dupré

The girl who took down the governor used her fame to land the cover of Playboy and turn her scandal into a paycheck. Spitzer’s call girl is now a sex columnist.

3. Kayte Walsh

Kelsey Grammer announced the engagement to his new little lady before the ink was dry on the divorce papers to his wife of 13 years. Either they got very close very quickly, or...

4. Michelle "Bombshell" McGee

This tattooed stripper stole Jesse James from America’s sweetheart, and has been cashing in with inflated lap dance rates.

5. Kacey Jordan

Privy to Charlie Sheen’s 36-hour bender, an impressive feat, Kacey Jordan and Sheen wildly went where no self-respecting people should go. Now, as part of her public due diligence, Jordan will star in a film venture (of the adult genre) scoring her a rather large sum of money.

6. Angelina Jolie

After co-staring with every-woman’s-nightmare in Mr. and Mrs. Smith, Hollywood’s hottest hunk left his wife of five years for Jolie. The pair now resides with their diverse family of six children.

7. Sienna Miller

After the actress’ highly publicized affair with Balthazar Getty (remember those topless photos from Italy?), Miller was able to move past her ex Jude Law’s affair, and the two are now planning a wedding for later this year.

8. Maria Chapur

South Carolina’s former governor and father-of-four, Mark Sanford's affair with Argentinean beauty Maria Chapur was exposed when he went missing for several days in the summer of 2009. Back then, he called Chapur his "soul mate," although stating that he’d "try" to fall back in love with his wife. Recent photos of the couple in Uruguay proved this was not the case.

9. Rielle Hunter

This actress/producer gained notoriety after her affair (and subsequent pregnancy) with vice-presidential nominee John Edwards was exposed -- even though both parties tried to hide it by claiming she was pregnant with the child of one of Edwards’ former campaign staffers. On January 21, 2010, Edwards finally admitted publicly that he is the father of Hunter's daughter Quinn.

10. Erin Barry

Basketball star Tony Parker’s alleged mistress, Erin Barry, may be the one to blame for Tony’s split from Eva Longoria. Though Tony denied any sexual activity, he couldn’t refute the “sexting” rumors, ultimately leading to his split from Eva.
