Eva Longoria Involved in Minor Fender Bender

A guy in West Hollywood hit the jackpot this afternoon when he scored Eva Longoria's phone number ... but that's because she had just rear-ended him with her BMW ... TMZ has learned.

According to our sources, Eva was leaving her BFF Ken Paves' salon when she pulled out into traffic and lightly tapped the car in front of her. We're told the car Eva hit only suffered minor scratches.

Our source on the scene said the guy didn't care about the minor damage ... he was just stoked to get Eva's digits.

Stranger things have happened.
