Peter Andre is reported to be furious that a party held by Katie Price for the fourth birthday of their son turned into an all-day drinking session, according to reports.

A friend from the party told sources that Peter phoned their Surrey mansion from China on Saturday, during a break in promotional work. He was reportedly livid to discover that the party was more about Katie's friends than Junior's birthday, and that everyone was drinking and swearing around the kids.

The guest from the event said, “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.

“Instead of being a fun-filled family day, it was attended by her mates, was pretty raucous and there was booze and bad language being bandied around.”

The four-and-a-half year relationship between the Katie and Peter has soured rapidly since their split last month, with both parties now refusing to speak to one another.
