Eva Longoria-Parker and her rumored cheat of a hubby, Tony Parker, are sleeping in separate bedrooms after a squabble while out with friends turned ugly. Topic of discussion? Blowjobs.

Chris Ramirez, an alleged friend of The Parkers, tells Star Magazine about the fight, which took place during a Tex-Mex dinner:

“We were all having a really nice time… I don’t know how it happened, but the conversation got dirty fast. Someone said oral sex should only be between man and wife. Then Tony chimed in, ‘A mouth is a mouth. What’s the difference?’”

Eva became enraged: “I can’t believe you said that! What do you mean, you’d take oral sex from anyone?”

Eva slapped her husband across the shoulder, hit him upside the head, and continued to “drink like a fish” for the rest of the evening.

Star claims the “doghouse” is a separate bedroom for Tony, where he keeps photos of the Spurs and his clothing because, “Eva takes up two closets in the master suite, so there’s no room for his clothes.”
