He's a multi-media star!
Kourtney Kardashian brought along brand-new boy Mason Dash Disick for a surprise visit to the studio for Ryan Seacrest's KIIS-FM radio show. It's the first radio "interview" for Mason, who was born Dec. 14.
Also along for the chat: Kourtney's sister Kim and their mom Kris Jenner.
"How cute is baby Mason?!" Seacreast asks.
"Is baby ready to feed? He's looking for your breast." he notes, volunteering himself as a "babysitter" for the little boy, whose father is Scott Disick, boyfriend to Kourtney, 30.
"I take Mason everywhere with me," Kourtney says on her blog. "We had to stop in and surprise Ryan!"
