The singer was snapped looking rather dapper in a three-piece suit as he headed to the BBC Radio 1 studios in London on Wednesday morning (29 January).
Peter looked quite tired (well, he does have a three-week old baby at home!) but flashed a smile for the photographers – and it's no wonder as life couldn't be better for him right now!
'Mysterious Girl' singer Peter announced his engagement to trainee doctor Emily MacDonagh at the start of this week, shortly after they welcomed their first child together, a baby girl.
And his professional career is going from strength-to-strength as Peter has penned a song for upcoming Dreamworks animated movie Mr Peabody and Sherman, which features the voice of Modern Family's Ty Burrell.
Peter, 40, became a dad for the third time on 7 January when Emily gave birth to their daughter at Musgrove Park Hospital in Taunton, Somerset.
He is already father to son Junior, eight, and daughter Princess, six, from his marriage to ex-wife Katie Price.
Nearly three weeks after her arrival, the latest Andre has yet to be named. Peter and Emily have said they want Junior and Princess involved in the decision, though, so we can't wait to see what they come up with!
Baby Andre-MacDonagh arrived a bit earlier than expected. News of the birth was first leaked via Twitter on 9 January by fellow hospital visitors who claimed to have seen the famous couple in the vicinity, before Peter confirmed it via Twitter.
Peter wrote: "Now that I have had the opportunity to tell Junior & Pringles, we are very happy to announce the safe arrival of our beautiful baby girl:) " he said. "We are extremely thrilled and mum and bubba are doing fine. We are looking forward to a nice quiet couple of weeks getting to know our baby (sic)."
After being inundated with messages from fans, proud new dad Peter tweeted: "A massive massive thank you to everyone who has sent congrats and well wishes. She's such a beaut. Love you all lots."
