Eva Longoria Regrets Not Dumping Tony Parker the First Time He CheatedNaughty But Nice Rob
Friends of Eva Longoria tell me everyone's favorite 'Desperate Housewife' is devastated about her split from Tony Parker, her husband of three years -- but her biggest regret is that she didn't leave him sooner.

"Once a cheater always a cheater," a friend of Eva's tells me. "Just five months into their marriage, reports of Tony's infidelity spread like wildfire, but Eva chose to listen to her heart and not her head. She stood by her man, believing deeply in the institution of marriage. She chose to believe her husband was innocent."
