Zac Efron and Michelle Rodriguez are dating. Media have declared them officially a couple after they were photographed getting close during an Italian vacation. Rumors that Zac Efron is dating actress Michelle Rodriguez now that model Cara Delevingne is single have been popping up all over the internet.

According to Us Weekly, Efron met Rodriguez at party she threw in 2011 and the pair have been hooking up ever since. "Fast and the Furious" star Michelle Rodriguez used to date mysterious model Cara Delevingne.

Is Vanessa Hudgens upset over Zac Efron's budding romance with Michelle Rodriguez? "Of course [Vanessa] knows about the pictures and [Michelle and Zac] being a couple," a source told  HollywoodLife.com. "But she is very happy in her own relationship and has moved on from Zac."

Us Weekly reports that shortly after Zac split from his longtime girlfriend Vanessa Hudgens in 2010, he started a relationship with Michelle. And they've been hooking up sporadically ever since.

"Whenever they're together and both single, they hook up," the insider told HollywoodLife.com.

"During The Rover after party, they hung out all night and really bonded with each other on a whole new level," an eyewitness told HollywoodLife.com. "They both had something to bond over. He was there for her breakup and she was there for his substance issues and that bond has turned romantic."

E! News quoted a source saying "Michelle is super-cool and laid back, and Zac has always been attracted to her because of that," a source told E!

The source continued "She's one of those people that everyone likes, she just gets on with all kinds of people and doesn't take the fame thing too seriously. Zac likes the fact that she is laid back, and he can relate to her. He is attracted to her great attitude. They understand one another."

The "Fast & Furious" starlet has been romantically linked to both men and women in Hollywood over the years, most recently to model Cara Delevingne. Rodriguez and Delevingne were first seen kissing at a basketball game in February, the same month Rodriguez confirmed the relationship rumors.
