You just never know who's going to show up to the same Halloween party!
Zac Efron and Sami Miró stepped out at Treats! annual Halloween celebration Friday night at the Los Angeles Theatre where the twosome looked happier than ever.
As the High School Musical star sported a white mask and Miró donned denim-on-denim, the twosome held hands as they celebrated the spookiest night of the year.
Zac and his girl were "inseparable," an eyewitness told E! News of Hollywood's hot new couple. "He looks very in love with her."
And even when Michelle Rodriguez arrived at the star-studded party, sponsored by Absolut Elyx, Efron and Miró continued to enjoy their festive night. Leonardo DiCaprio, Ryan Seacrest, Robin Thicke, Paris Hilton and Derek Hough were also in attendance.

Efron and Rodriguez briefly dated for two months this past summer. The Fast and the Furious actress and her man made headlines after they were spotted cuddling and kissing one another on a yacht in Sardinia.
At the time, a source told E! News that "something changed" during their two-week vacation, which resulted in them becoming more than just friends. Their romance, however, fizzled before the end of August.
Today, Efron appears to be smitten with Miró who just signed with Los Angeles-based modeling agency, DT Model Management.
In addition to spending time together in the states, Miró also joined Efron for his birthday trip in Amsterdam.
"They were acting very much in love, she kept hugging him," an eyewitness told E! News. "Their love looked genuine."
