The 'Mysterious Girl' singer, 43, had promised one lucky fan a dream day out as part of a Twitter competition and, true to his word, he whisked Catherine Pritchard from Plymouth off to London for an afternoon with him and pampering day.
Jealous of both, right?!
Catherine won the Oykos competition, which asked people to explain how the brand's new Whip 'n' Mix made them feel, with a cheeky tweet about Peter which read: "I have certainly whipped myself into a frenzy over you for the last 15 plus years! Definitely tasty in more ways than one!"
"I had such a great time spending the day with Catherine," said Peter.
"It was a close call but her Tasty Tweet really gave me and the team a giggle so I couldn't wait to meet her. We had a great time chatting away and it was fantastic to see that she's just as cheeky in person as she is on social media!"
Peter's known for being great with his fans. He once surprised a fan by turning up to her house as part of an ITV's This Morning segment in November 2015, while that same year he treated 14-year-old fan to tickets for a concert after hearing she'd undergone six heart operations.
Meanwhile, in other Peter news, he announced this week he's joining Loose Women for the summer!
He wrote his his new! magazine column: "I'm happy to announce I'll be on your telly on Loose Women quite a bit over the summer. I won't be a panellist, I'll be a roving reporter giving a man's point of view on many of the subjects.
