Zac Efron doesn't appear to be single anymore! The 26 year-old actor seems to be the latest person involved in the love life of Michelle Rodriquez.

Efron was spotted sharing a kiss with the 35 year-old actress while enjoying a vacation in Sardinia, Italy, on Saturday (July 5th). The unexpected couple were not shy in sharing PDA moments in front of their friends as they appeared to be constantly by each other's side.

The 'Fast & Furious' star has recently been linked with British model Cara Delevingne, but she is very open about her attraction to both genders. "I've gone both ways. I do as I please. I am too ... curious to sit here and not try when I can," she told Entertainment Weekly in October 2013. "Men are intriguing. So are chicks."

During the duo's boat trip with their friend Gianluca Vacchi, Efron was seen shirtless, sporting only a pair of green shorts and displaying his muscular physique. Rodriguez was wearing a revealing black and white bikini that showed off her physically fit figure.

What makes this pairing more surprising is that the 'Avatar' actress has previously dated the likes of Vin Diesel, and stated that she prefers "manly men," which Efron doesn't appear to be. "It's the way my DNA is just built for that alpha male kind of chemistry," she told NY Daily News. "It's hard for me to look at this new generation of men and feel as attracted."

Efron was recently linked to "Bad Neighbours" co-star Halston Sage, and was involved in a very publicised four-year relationship with Vanessa Hudgens that ended in 2010.
