Peter, who recently became a dad again after his fiancée Emily MacDonagh gave birth to daughter Amelia, was pictured outside Radio 2 and he gave photographers a smile as he headed inside.
The proud dad spoke about Emily and Amelia on the radio show, saying that last month was "incredible" thanks to them both.
Peter said: "January was an incredible month because I got engaged to beautiful Emily and we had a beautiful baby girl three weeks early. Nothing tops the birth of a child.
"It really was an incredible moment, that's for sure. She's beautiful."
During Emily's pregnancy, Peter announced he was quitting his reality show Peter Andre: My Life.
And, although he appeared on I'm A Celebrity...Get Me Out Of Here! in 2004, it seems that his reality career is well and truly over.
Peter said: "Celebrity Big Brother is one of those shows which everyone is glued to watching but I don't know if I'd be setting myself up for a fall going into that situation. I don't know if I'd cope.
"With I'm A Celebrity, you're in the jungle, you've got trials to do to try and earn food. There are some great reality shows out there but I think I've overdone them now. You're probably all sick of me!"
Also this weekend, Peter was quoted in an interview with the Daily Express saying that he wants more children with Emily.
