But your jaw might bust right through that floor when you hear how long they've supposedly been hook up buddies!
While the two have only recently been caught by paparazzi locking lips, it appears that the liplocking started back in 2011 when they met at one of Michelle's parties, after Zac had split with Vanessa Hudgens.
"Whenever they’re together and both single, they hook up."
Hey, no shame in that!
But don't think that this will turn into some longtime loving as the insider added:
"They’re just having fun on vacation."
So that means Zac is still free for some fun???
We likey the sound of that!
