Zac Efron & Vanessa Hudgens spotted kissing?

A report has hinted that Zac Efron and Vanessa Hudgens could be back together – after the pair were reportedly spotted kissing at a club.

It was reported last month that the couple of nearly four years had parted ways, however they were spotted together on Friday at Los Angeles nightclub Eden

“The two showed up around 10:45 p.m. through the back entrance with a group of friends and were holding hands at different points throughout the night,” a source told UsMagazine.com.

“They were kissing on the lips and seemed to be enjoying their night,” says the source. Adds another eyewitness: “They seem to be back together.”

Apparently they were trying to keep the public displays of affection under wraps, with Vanessa reportedly pushing Zac away when someone tried to snap a photo of them together on a mobile phone.
