Michelle Rodriguez's ex Zac Efron is dating again but as he's spotted several times with Sami Miro, but rumors are flying that the relationship is not serious.

The Us Weekly said that Michelle Rodriguez's ex Zac Efron and Sami Miro are still in the stage of getting to know each other.

"Zac is dating Sami but it isn't serious," the source told the magazine.

Reportedly, Zac Efron and Sami Miro were spotted at the Dodgers vs. Giants game at the Dodgers Stadium in Los Angeles on September 22. They were also snapped in Copenhagen, Denmark on October 11 when they coordinated their look with aviator sunglasses and black sweatshirts.

On October 14, a black and white snap of Zac Efron and Sami Miro was updated to the actor's WhoSay account on October 14, along with the caption: "Thx to @ReneRedzepiNoma and team @Nomacph. You've created a sophisticated, one of a kind culinary experience I'll never forget. You rock!"

In the report from E! News, Michelle Rodriguez's ex Zac Efron and Sami Miro have been spending a lot of time lately.

"The pair was spotted grabbing a meal at FoodLab in Los Angeles on Friday afternoon, and Efron was overheard introducing Miró to a fellow patron as his 'girlfriend,'" it said.

And the vacation in Copenhagen could also be an advance birthday celebration for the hunky "Neighbors" star who turns 27 on October 18.

Zac Efron had just come from a relationship with Michelle Rodriguez and it was reported that they split amicably because they were just having fun.

"It had just been a casual hookup for Zac and Michelle. They were having fun. She is such a great person and he naturally gravitated towards that. They saw comfort in each other and connected on their experiences in rehab and were really good for each other," the source told E!.
