Eva Longoria and Nicollette SheridanWhile Nicollette Sheridan's credibility is being questioned in her lawsuit against 'Desperate Housewives' creator Marc Cherry, who she said struck her across the face on set, castmate Eva Longoria Parker has admitted that while she didn't witness it, she was aware of such an incident.

"I know they did have a thing on set," Longoria Parker said on Ryan Seacrest's radio show Wednesday, according to PEOPLE. "I guess it was a couple years ago," she continued. "I wasn't on set when it happened but apparently this incident had happened and she felt it was wrong."

Longoria Parker didn't have many details, but added that Cherry "probably could not harm a fly."
