Ross Lynch Reunites With 'Teen Beach 2' Co-Stars Before R5's Pomona Show

Ross and Riker Lynch light up the stage during their concert at the Fox Theater on Friday night (January 29) in Pomona, Calif.

The two R5 bandmates and brothers rocked out with siblings Rydel and Rocky, and Ellington Ratliff after their younger brother, Ryland and Parade of Lights opened the show.

Just before the show started, Ross reunited with his Teen Beach 2 co-stars Chrissie Fit and Grace Phipps backstage.

“This rockstar, @rossr5, absolutely killed it tonight! So much fun at the @officialr5 show,” Chrissie wrote on Instagram with a pic.
