In January, Catherwood was selected to fill in for Regis Philbin on "LIVE! with Regis & Kelly."
The guest host gig helped start the ball rolling on his latest job.
"I accidentally stumbled with Regis & Kelly, that had a lot to do with this," Catherwood said. "Here I am, not going to turn it down, you know?"
Catherwood will juggle his dance duties with his dual radio jobs at KROQ, both in the morning with "Kevin & Bean" and in the evenings with Dr. Drew Pinsky on "Loveline."
His day jobs may not cater to the exact "Dancing With the Stars" demographic, so Catherwood's not sure who might become his core group of fans.
"Whatever part of the audience wants to support me, I'll take it," Catherwood said. "Lord knows I'm not going do it on my dancing ability and I don't have the name, so if someone wants to support me, by any means necessary. Thank you.
"I'm a disaster on the dance floor. I'm exponentially worse when it comes to social situations."
Season 12 of "Dancing With the Stars" kicks off Monday, March 21 at 8 p.m. PT.
