Single gals of Australia, you might want to grab a tissue box…

A crazy new Report Claims Zac Efron and his girlfriend Vanessa Valladares are engaged.

Yes, you read that right! The rumour is Zac secretly proposed to his Aussie girlfriend during his star-studded birthday bash earlier this month.

Woman’s Day is claiming, “He gave it to her after the party – it was incredibly romantic.”

“Neither of them are saying much about it, but there’s no doubt it was some kind of unofficial engagement,” the source continued.

Zac and Vanessa are yet to comment on the rumoured engagement so, this could just be the rumour-mill sending fans into a tiz.

Time will tell, but we are so here for a Byron wedding, right?!
