Jessica Simpson doesn't believe in staying friends with 'the ex,' and her good pal Eva Longoria found that out the hard way.
When Simpson found out Eva had been hanging out with her ex John Mayer the other night at Gold Bar on Broome Street, she "went nuts," according to the NY Post.
"When Jessica heard that Eva was being friendly and polite to John, she called her a back-stabber and was furious."
Naturally, Simpson's rep denied the rumors but I can totally picture Jess going nuts over something like that. She seems like the jealous ex girlfriend type doesn't she?
