All Rise For Eva!!!

Eva Longoria could be deciding who is responsible for a rear-ender!

TMZ spies spotted the "Desperate Housewives" star in the jury assembly room Monday at the downtown Los Angeles County Courthouse.

Longoria was dressed to impress in a tan coat, tight blue jeans, lookin' "smokin' hot." Our spy has to be hosed down after watching Eva yak it up on her cellphone.

Longoria was friendly enough to her fellow potential jurors, but we're told she hasn't been selected as a potential juror on a specific case.
