Attention all you cougars out there (I’m talking you, recently-separated Elizabeth Hurley) – Zac Efron is now a single man.

It’s just been announced that the 23-year-old actor and his High School (Musical) sweetheart, Vanessa Hudgens, have broken up. They’d been together since 2006.

According to an insider, the split had nothing to do with another person. "They were together for so long. It just ran its course."

"They are 100 percent still good friends," a People source added.

This news comes just one day before Hudgen’s birthday. She turns 22 tomorrow.
