Madelaine Petsch Didn’t Know What ‘OTH’ Was When Chad Michael Murray Joined ‘Riverdale’

Team Lucas Scott? Not so much! In fact, Riverdale star Madelaine Petsch didn’t actually know what “OTH” was until Chad Michael Murray joined the CW drama this season.

“I didn’t watch OTH, no — which is what he calls it. He’s always like, ‘OTH.’ I’m like, ‘Wait, what is that? Oth? What does that stand for?'” the actress, 24, admitted to Us Weekly when stopping in to our studio to promote her new M3 sunglass collection at Privé Revaux. “He’s like, ‘One Tree Hill.’ I was like, ‘Oh yes, the show you were on. Yes. Great.’

The actor, 37, starred on One Tree Hill from 2003 and 2012, something that paid off when it came to working on Riverdale.

“He gives me a lot of really great advice which I love, and he’s so kind. He’s such a professional. He fit in with all of us perfectly. I don’t know how our casting director does it, but he puts together a flawless group of people that just seamlessly fit,” the Teen Choice Award winner added. “There’s no drama. Everybody likes each other; everyone’s nice.”

The finale of Riverdale airs on The CW Wednesday, May 15, at 8 p.m. ET.
