Katie Price denies Peter Andre his children

Peter Andre is furious with Katie Price for refusing to let him see his children at the weekend only to go out partying.

The Mysterious Girl singer's request to see the children they raise together - Harvey, seven, Junior, three, and 23-month-old Princess Tiaamii - was turned down by his estranged wife on Saturday (30.05.09), meaning they were put to bed by a nanny while Katie reportedly went out and got drunk.

The glamour model - known also as Jordan - was spotted drinking champagne while she watched boy band Boyzone perform at London s Wembley Arena on Saturday night.

Afterwards Katie, who also seen drinking alcohol at the Clothes Show Style Awards on Friday (29.05.09), headed to a gay club in the UK capital to continue partying.

A source told Britain's Daily Mirror newspaper: "When he found out Kate was working late on Friday, he argued it would make more sense for the children to stay with him.

"But Kate refused, insisting they stick to their routine. Understandably Pete was livid when she went clubbing and drinking on Saturday, leaving the nanny with the children.

"He just wanted to give them all some quality time. Junior in particular has taken the split really badly."

An onlooker who saw Katie, 31, at the concert on Saturday told Britain's Daily Star newspaper: "She was all over the place and it looked like she was flirting with a guy. She was having fun but appeared to be very drunk. Maybe it's just her way of coping."

Katie's agent has denied any claims of wild behaviour, saying she was simply having a good night out with friends.

The couple - who split three weeks ago - have both met with divorce lawyers and are expected to legally split within the next six weeks.

Katie is reportedly set to agree to Peter's divorce petition, which will cite her "unreasonable behaviour", as it will speed up proceedings.
