Katie Price reportedly showed up at Peter Andre’s house unannounced this week, shouting in a fit of temper.

Katie and Peter have barely crossed paths since their split last May and when they do, it’s by appointment only. However Katie showed up at his door on Monday, demanding that his staff let her in.

Thankfully Peter and their children weren’t at home at the time of the altercation.

A source told The Sunday Mirror: “Katie just showed up unannounced. She was mad and manic, and kept screaming: ‘Where’s Pete?’

“I don’t know what it was about – just that it wasn’t about their children, who were with Pete by prior agreement. But she should not have turned up like that without an appointment.

“And when they told her he wasn’t there, she ­demanded they let her in to check.

“Someone got Pete on the phone to tell him what was going on, and he ordered the staff to get rid of her. She has become the ex from hell.”

Friends of Katie are now said to be convinced that Katie is trying to win Peter back and is becoming more and more obsessed by her ex.

A source said: “She cannot ­accept their relationship is over – she has to do things like this to grab his attention.

“Katie thinks everything is ­going wrong and blames Pete. She realises her life was better when they were together, and even now thinks everything would be all right again if they reconciled.

“Pete hasn’t found anyone else yet, so Katie cannot see why he doesn’t want her. But he won’t speak to her on the phone.”

A spokesman for Katie claimed: “Katie did go round to Pete’s on Monday, but it was to pick up a passport for Princess Tiammii.

“She was going to Manchester on Tuesday and she ­needed ID, which Pete had, for Tiammii for the flight to Manchester.”
