Meet Katherine McNamara and Mark Indelicato — the newest cast members of Madison High!

You may remember Mark, 16, from ABC’s Ugly Betty. He’ll be playing Harvey Flynn, the overly officious stage manager and reigning president of the Drama Club.

Katherine, a Broadway vet has been cast as Cherry O’Keefe, Madison High’s resident queen bee and blogger.

The duo join Luke Benward, Leah Lewis, Nolan Sotillo, G Hannelius and Alyson Reed. The cast has already had several bowling parties together!

Now that you see the whole cast — what do you think? Will you watch Madison High?

Ugly Betty star Mark Indelicato got his first full taste of Fashion Week this week.

The 15-year-old actor blogged about his day shadowing Andrew Beven around the tents in Bryant Park on TeenVogue.com.

Mark shared at one point, “Keeping up with our tight schedule we whisked into another cab going to the Bowery Hotel to see Alexa Chung for Madewell. We chatted with blogger Just Jared, and then had a moment with Alexa herself (one of Andrew‘s best friends)! We also reunited with some of the Teen Vogue team. When Jane Keltner remembered me I died a little inside but I had to pull it together and look professional, I mean I am Andrew‘s intern!”
