Ruby Rose & Bella Thorne Attend a Drive-By Birthday Party Together

Ruby Rose and Bella Thorne wear masks while stopping by a friend’s drive-by birthday party on Sunday afternoon (May 3) in Studio City, Calif.

The two stars arrived at the party in the same car and waited in a line-up of cars to help celebrate with birthday girl Riawna Capri.

Ruby and Bella hopped out of the car to grab some drinks and snacks from the catering table when they reached that point in the line-up.

Also in attendance at the drive-by birthday party were Ashley Greene and her husband Paul Khoury.

Riawna is one of the most in-demand hairstylists in Hollywood and she’s the co-founder of the popular salon Nine Zero One.
