Just like a ton of other celebs who flocked to Spain for the week, Zac Efron and Michelle Rodriguez are having a blast in Ibiza. The 26-year-old Neighbors star and his ladylove continued their vacation together Saturday, packing on the PDA on Justin Bieber’s yacht Friday. The duo was snapped locking lips passionately as Efron held the Fast & Furious star close, later cuddling with her during the evening.
