Zac Efron may be encroaching on Cara Delevingne's territory! The 'Neighbors' actor and Michelle Rodriguez was found kissing and sharing many PDA moments on their Italian holiday in Sardinia, him shirtless and her clad only in bikini. Where is Halston Sage? Is this a ploy to get Halston Sage jealous? Or could it be that Zac Efron is actually dating Michelle Rodriguez?

Michelle Rodriguez, clad in a bikini celebrated her fourth away from her former girlfriend Cara Delevingne and in the arms of Zac Efron, who has come long ways since his 'High School Musical' days.

Zac Efron has been reportedly linked to 'Neighbors' co-star Halston Sage for some time now, but it looks like things are about to change pretty quickly with hot Michelle Rodriguez in the picture.

And the 9 year age difference certainly didn't seem to phase the 'Neighbors' actor as he leaned in for hot smooches throughout the trip. Maybe Halston Sage was too young for him.

Michelle Rodriguez's decision to spend the weekend with the 26-year-old eligible bachelor may have been a smart decision. Her ex-girlfriend Cara Delevingne was having a wild time with her fans at the Wireless Festival in London, England.

But the potential couple hasn't just been whiling away their time making out on the Italian beach. They've also hard at working filming a home video of them dancing to DJ Snake and Lil Jon's 'Turn Down For What'.

The 35-year-old 'Fast and Furious' regular and Zac Efron were joined by choreographer Yousseff Giga and an Italian businessman by the name of Gianluca Vacchi.

When he wasn't shirtless and kissing Michelle Rodriguez, Zac Efron has been clocking in some hours working out so that he looks good in an European-style speedo on the beach. It paid off for sure! At least Michelle Rodriguez looks very satisfied that he is as hot as she is.

Do you think Michelle and Zac will make it as a couple? Let me know in the comments below!
