But could he be making a comeback?!
Well, it doesn't seem out of the question considering he wrote in his New magazine column this week: "I want to get something straight- I'm not quitting reality TV... Doing my own reality show is still a very strong option. I'd like to bring back the show for a year or two then leave it again for another four years."
Peter's definitely an old hand at reality TV having started alongside then-wife Katie Price in their own ITV2 series, followed by a string of spinoffs including their brief relocation to America. We watched their marriage, the arrival of the kids, their ups and downs, and more.
After the couple split in 2009, both went on to star in individual reality shows. For Peter, that was his The Next Chapter series followed by My Life.
Peter announced in September 2013 that production on My Life would be stopping, partly so he could focus on other projects, and because then-pregnant girlfriend Emily MacDonagh (now his wife) wanted to remain away from the cameras.
He also told ITV's This Morning he wanted to out on a high, rather than see ratings slip.
"I am with someone who is a lot more private and even though I am public and I could never ask for privacy here and there - that's wrong, you can't when you're in this industry - you have to also respect the other person. But it's not just that, I do honestly think that we've done it and the public have been amazing, and I would hate it for the ratings to start slipping and then I have to stop."
So, the big question is: if Peter does return to reality TV, will we be seeing Emily and their children with him? Emily did appear in My Life every so often, but cameras stopped rolling before the birth of their daughter Amelia. They have a second child on the way.
Peter's children with Katie - Junior, 11, and Princess, nine - have appeared on TV since they were born, but Amelia's always been kept quite shielded from the cameras.
