Sex addiction and cheating with strippers seem to be the hot trends in Hollywood lately. Matthew Fox is the latest celeb to cheat on his partner with a stripper and now it appears Ryan Phillippe may be a sex addict. A source close to Abbie Cornish says she dumped him because, “he has a Tiger Woods problem.” She moved out of the house they shared this weekend while he was off visiting a “lady friend” with his children, Ava and Deacon, by ex-wife Reese Witherspoon. Ryan has long been accused of having a roving eye and has already been hitting the clubs on both coasts. Abbie has been busy shooting the film Sucker Punch in Vancouver for the past seven months and apparently in this case, absence didn’t make the heart grow fonder.
