Riverdale's Casey Cott Supports Brother Corey Cott at Broadway Opening Night

Casey Cott suited up in his Sunday best for opening night of big brother Corey‘s new play in New York City this week!

Did you know that Casey, who stars on Riverdale, was related to Corey? We sure didn’t!

If you remember, Corey famously starred with Vanessa Hudgens in Gigi.

“So proud of my incredibly cooler big brother opening Bandstand on Broadway tonight!” Casey wrote on Twitter last night after the show. “Everyone give @NapOnACott the love. He’s mind blowing.”

Awww, so sweet!

Casey also brought girlfriend Stephanie Styles to Bandstand‘s opening night.
