Zac Efron and his new girlfriend Sami Miro happens to attend the same party that Michelle Rodriguez, whom Zac dated briefly, on Friday at the Los Angeles Theater. The said party is sponsored by Absolute Elyx which also invites other big celebrities in Hollywood, E! Online reports.

Zac, meanwhile, is wearing a white Jack The Ripper mask in attending the party.

Sami Miro came into Efron's dating life after he broke up with his two-month summer fling with the Fast and Furious star. The Los Angeles-based model is said to have been going out very often with the actor including their time spent in the US and his birthday in Amsterdam.

"They were acting very much in love, she kept hugging him. Their love looked genuine," another source told E! Online who claimed to have witnessed the couple in their PDAs.

It can also be remembered that Zac and Michelle Rodriguez's summer love hit the headlines as they are spotted hugging, kissing and cuddling while they were unwinding in a yacht somewhere in Sardinia on the Fourth of July weekend. However, the romance did not last long.

US Weekly previously reported that the couple are seen in a very heated argument in Ibiza, Spain which is said to be the cause of their split. The tabloid further said that the though the 27-year old actor still have strong feelings for Rodriguez but the actress 'wants to do her own thing.'
