Two mega-stars, one hotel.
Zac Efron, who will attend tonight's premiere of his new romance flick The Lucky One at Bondi Junction, did as any movie star would do after a long-haul flight from Los Angeles - he squeezed in a workout before enjoying a leisurely breakfast on his balcony ... sans clothes.
The High School Musical star even carried his own breakfast tray and hung out his used bath towels. So who says celebrities aren't just like us?
In town for the Australian premiere of her new flick Battleship tomorrow night, Rihanna, 24, landed on Saturday and announced her arrival, tweeting: "Hellooooo Australia!!!'
Later, she shared her Harbourfront views with her 15 million-plus Twitter followers, writing: "Happy Easter all the way from Sydney."
It's not known if the pair, who are reportedly friends, were aware of each other's presence.
The stars lead a wave of big-name international visitors in Sydney over the next two weeks.
Brit music sensations One Direction are scheduled to arrive in Sydney tomorrow morning, with the boy-band to make several appearances prior to their two concerts at the Hordern Pavilion on Friday.
And a swathe of the world's biggest hip-hop and R&B stars are due to begin arriving on Wednesday for Sunday's SupaFest at ANZ Stadium, including P Diddy and singer Chris Brown.
