Looks like Rihanna isn't the only one down under in Australia staying at the Sydney's Park Hyatt.
Zac Efron was spotted at the same hotel checking out his balcony... shirtless might we add!
The actor appeared to be in super chill mode enjoying a glass of OJ and listening to some jams on his handy dandy iPad.
The two are both in town for their movie premieres. Zac will be strutting down the red carpet for his flick The Lucky One while RiRi will be hitting the premiere for her role in Battleship.
No word on if the two are friends but we wonder if they'll cross paths and maybe share a drink...After all the Ashton Kutcher rumors, it doesn’t seem like the former Disney star, Zac, is too far from her type.
