Zac Efron And Michelle Rodriguez Are A Good 'Influence On Each Other'

The unlikely couple's Italian host assures there' s no need to 'be concerned.'

It's not just that Zac Efron and Michelle Rodriguez are one of the more unexpected celebrity couples to hook up in recent memory -- the ab-licious "High School Musical" grad and the feisty "Fast and the Furious" star are a study in opposites -- but their awkward coupling is also apparently cause for concern in some corners of the Internet.

This week, the matter boiled to the level of "hot topics" when blogger Perez guested on Wendy Williams' show. After sharing his theory on what drew the unlikely duo together in the first place -- *clears throat*, summer fling -- the gossip gangsta said that he was worried bad-girl Rodriguez would be a bad influence on fresh-from-rehab Efron.

Zac and Michelle were first spotted smooching over the Fourth of July wekend on a yacht in Sardinia. Their PDA-filled Italian adventure continued in the club, where the pair were again caught kissing. Their host, businessman Gianluca Vacchi, thinks we should be cheers-ing to the actors' newfound dolce vita. In fact, he took to Instagram on Friday (July 11) to say that the daytime talk show segment had given him a good chuckle.

"Don't be concerned, Z and Mich have a mutual healthy influence each other and they are very cute toghether," Vacchi wrote alongside an clip from the "WW" show.
