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.
