How's this for a transformation? In a recent snap on Instagram Peter looks reminiscent of jungle dweller Tarzan. Maybe he's missing his days on I'm A Celebrity.
Before everyone starts questioning what miracle vitamin is responsible for this sudden hair growth, we should point out he's wearing a wig.
The singer and presenter did actually look verrrry like this once-upon-a-time, check out the Mysterious Girl video if you want to see the real deal. And a lot of bare-chest under a waterfall action.
Here's a snap of Peter with his actual hair-do, which is perfectly preened.
Peter recently enjoyed a winter sports break in Canada with fiancée Emily MacDonagh and his kids, daughter Amelia, one, and Junior, nine, and Princess, seven.
Wonder what newly-qualified doctor Emily thinks of her beau with all that hair? Pete has said they plan to marry no later than May 2016, maybe he's been looking through the archives for some wedding inspiration.
Dad-of-three Peter is currently presenting Give A Pet A Home, alongside Amanda Holden, where celebs help to rehome abandoned pets, aww.
