With his estranged wife Katie Price moving on very publicly with her new man Alex Reid, a downtrodden Peter Andre could barely hide his distress Saturday night on what a friend described as probably "the worst day of his life."
The reality star and singer was said to be "horrified" after seeing graphic photos of Katie Price kissing Alex Reid - in front of his children this time.
A source close to the depressed Andre, 36, said: "He is more upset than I have seen him since he left Kate - this really is the worst day of his life."
Peter also accused Katie of being a "despicable mother" when he heard her use profanity in front of the kids and encourage them to mimic her.
But sources say it was the latest batch of pictures of Katie cavorting with cage-fighter Alex Reid as her children with Peter played nearby, all the while being filmed by a camera crew, really set the depressed Peter over the edge.
Needless to say, Peter Andre is not a fan of Katie Price. Or Alex Reid.
A source close to Peter told the Daily Star: "He couldn't believe it when he saw the photos of his kids being fathered by this man he has never even met."
"For [Katie Price] to introduce him to the kids is hard enough. But behaving like a pair of teenagers right after their dad leaves is another thing altogether."
During a row stuffed full of expletives, Peter branded the giant-breasted model known as Jordan a "despicable mother" and said she was a "disgrace."
Having been married to her for some time, you wouldn't think this would be altogether shocking, but she does seem to be rubbing it in his face pretty hard.
