Zac Efron and Taylor Schilling Pictures at Melbourne Premiere of The Lucky One

Zac Efron hit the red carpet at The Lucky One premiere in Melbourne last night with his lovely co-star Taylor Schilling. Fans went wild for Zac at Monday's premiere in Sydney, where he joked about sharing his hotel with Rihanna. Zac and Rihanna spent time relaxing on the balcony of their respective suites at the Park Hyatt. Rihanna snapped photos of the picturesque scenery while Zac took off his shirt and flashed his well toned abs. Zac's stay Down Under is winding down, and he's expected back in the States this weekend for additional press prior to Monday's star-studded LA screening.
