Whatever the case is, they definitely looked like they were more than just friends when they were spotted making out while at L.A.'s newest club, Club Eden, on Friday night.
"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 tells Us Weekly.
"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."
At one point Vanessa saw a random partier try to snap a photo of them making out and she quickly pushed Zac away. Why are you guys teasing us like that?! I can see these two definitely just being friends with benefits, but than again, it can't be easy walking away from a four year relationship with no feelings.
