Just weeks after Michelle Rodriguez and Zac Efron sparked rumors of a relationship after they were spotted making out in Italy, the couple was at it again Thursday night, this time at a nightclub on the Spanish island of Ibiza.

The two were reportedly locking lips on the dance floor, and, according to TMZ, Efron appeared to be holding a beer bottle. He may have just been holding it for Michelle, who was spotted with it moments before. The actor completed two stints in rehab over the past year, so hopefully he wasn't drinking.

Michelle was spotted aboard a yacht with singer Justin Bieber on Wednesday, hanging out and doing some jumping off the back of the boat with some pals before Efron arrived in town.

Bieber, meanwhile, was hanging out and getting close with model Shanina Shaik on the upper deck, but after posting a selfie with the model he wrote, "Me and the beautiful @ShaninaMShaik, and don't even start with dating rumors."
