Mel Gibson's on a roll ... a week after getting up close and personal with Maria Menounos -- the actor surfaced by the beach in L.A., planting a big smooch on an unidentified woman.
The photo was snapped yesterday outside a beach house in Santa Monica.
Mel's been on a tear in the lady department recently -- sweeping Maria Menounos off her feet at her 34th birthday party last Sunday in Encino ... literally.
Mel was even spotted last month at a Victoria's Secret party in Beverly Hills -- chatting up a mystery blonde.
Who knows, maybe they're all just "Passion of the Christ" fans.
