Zanessa, the on-and-off screen couple celebrated Vanessa’s big day with close friends including  Ashley Tisdale, Monique Coleman and Chris Warren, Jr. at East Restaurant and Bar and according to JustJared Junior it was a surprise birthday party.

Before Vanessa’s actual big day, she spent the weekend with her beau, Zac as we reported. They went to the gym together in their black hoodies on Saturday evening. Sunday, they had lunch with their friends and went shopping! Not sure if Zac picked up something really special for his girlfriend’s birthday but I bet he did.

What do you think Zac got Vanessa for her birthday? It’s a wild guess I know but it’s fun to give it a try..
