Michelle Rodriguez and Zac Efron were spotted locking lips on July 6 during their trip to Sardinia. The duo was reported taking a flight together with a private jet to Sardinia, Italy on Thursday. They were accompanied by Italian businessman Gianluca Vacchi.

In some pictures obtained by Fan Girl, the "Neighbors" actor and the "Fast and Furious" actress were locking lips on a yacht and also showed a lot of PDA without hesitation.

Michelle posted a video on Thursday to celebrate the Independence Day of America. The Instagram video showed her swimming while bringing an American flag on her hand. The video was recorded by a man whose voice was said to be Zac's. The "Battle: Los Angeles" actress captioned the video with, "Happy 4th America."

Report of Michelle kissing with Zac spread just a month after the bisexual actress was reported having a relationship with supermodel Cara Delevingne. Back in June, Cara opened up about her reason for having a same-sex relationship during an interview with The Telegraph.

The 21-year-old model said, "I don't meet men now who just want to be my friend. It doesn't really happen that much. They're shallow like that. Most guys are not like, 'Oh we should just be mates.' I think it's harder to be friends with guys because guys just want to have sex with you." When talking about her relationship with Michelle, Cara stated, "I know what people are doing who are my age; I just think it would be a lie to pretend that I'm not having a good time."

There is still no confirmation from Michelle or Zac if they are in a relationship.

Michelle will next be seen in "Fast and Furious 7". In the seventh installment of "The Fast and the Furious" film series, she stars along with Vin Diesel, Paul Walker, The Rock and Jason Statham. The movie will be released in the U.S. on April 3, 2015.
