Earlier this week, the website TWIST claimed that the two had a great time together at the Hollywood nightclub Eden.
According to a source, Vanessa and Zac were “bopping around with her arms up while Zac had his hands all over her! Vanessa had a smile on from ear to ear and the two were inseparable… Zac sat in between her legs and she wrapped her arms around him.”
But Hudgens’ rep denied the speculation, telling Celebuzz that it’s not the case.
“That TWIST story can’t be true seeing as how Vanessa is out of town working on a film,” her rep said.
Zac and Vanessa split in December 2010.
