Michelle Rodriguez & Zac Efron Kissing -- Hot Italian Vacation (PHOTOS)

Michelle Rodriguez is rebounding just fine from her supermodel ex-GF -- just ask Zac Efron's mouth ... which got all up in Michelle's grill during their Italian vacation.

35-year-old Michelle was spotted sucking face with the 26-year-old "Neighbors" star off Sardinia while aboard a yacht owned by of one of Zac's multi-millionaire pals.

You could say Michelle -- who's been open about her bisexuality -- is getting a little revenge. Last month, her ex Cara Delevingne was making out with model Karlie Kloss.
