Peter Andre is furious Katie Price turned their son's fourth birthday in an "all-day drinking session".
The 'Mysterious Girl' singer is reportedly no longer speaking to his estranged wife after she got drunk and invited all her friends to Junior's party at their marital home in Woldingham, Surrey, on Sunday (14.06.09).
The 36-year-old star - who didn't attend the bash because he was promoting his new album in China - was so angry, he phoned Katie and screamed at her in front of all her guests, accusing her of spreading malicious stories about him.
A partygoer told Britain's Daily Mirror newspaper: "This row was something else. Kate is adamant Pete's camp have been leaking stories about her. And he feels she's been issuing a smear campaign against him. But what really tipped Pete over the edge was when he discovered who was invited to Junior's special day.
"Instead of being a fun-filled family day, it was attended by her mates, was pretty raucous and there was alcohol and bad language."
Peter returns to the UK today (16.06.09).
He is expected to drive straight to Katie's house to pick up their two children Junior, and 23-month-old Princess Tiiaami, who he will take on holiday to an undisclosed location.
His spokesman said: "Pete just wants to see his kids and get on with his career."
Katie's seven-year-old son Harvey, from a previous relationship, is expected to remain with his mother. Katie recently revealed she was "over" Pete and saw Junior's birthday party as a chance to "move on".
She reportedly told one partygoer: "I'm so over Pete. This has been all about moving on with my life. The party was all about me, my friends and the kids, nothing else."
