Arctic Monkey's Alex gives Pixie Geldof the cold shoulder

Snubbed: 16-year-old Pixie got an icy blast after she tried to move on on Artic Monkey Alex Turner

Artic Monkey Alex Turner is the man of the moment, so it was only a matter of time before one of the Geldof sisters had a crack at him.

But Pixie's attempts to attract his attention at an East London party last night ended in embarrassment for the youngest daughter of Sir Bob.

Alex was having none of it, and humiliated her by totally blanking the 17-year-old wannabe model in front of all her pals.

He arrived at the Sony Walkman Hidden House Party at The Roost in Dalston with bandmate Matt Helder to watch his girlfriend Alexa Chung's DJ set.

A source said: "He was walking up the stairs when an excited Pixie ran after him and called his name. She was desperately trying to get his attention, but he totally blanked her.

"But she wasn't deterred. Later, as Alex and Matt watched the performance by Dizzee Rascal, she and a few of her pals positioned themselves right in front of them in the crowd.

"She tried a few dance moves and tried talking to him, but he wasn't interested. He didn't even respond to her, poor Pixie, he just totally ignored her.

"She was mortified and stormed off in a huff."

It looks like Alex only has eyes for T4 presenter Alexa.

Also at the bash was Mighty Boosh star Noel Fielding, who felt it necessary to wear a native Indian headdress as he did his DJ set.

He finished it early, and had plenty of time left to enjoy the party, celebrating the launch of the new Walkman range.

Razorlight's Johnny Borrell also made a brief appearance, as did Pixie's sister Peaches, who turned up late.

But the random celebrity of the night had to go to the stunning Heather Graham, in town for the BFI London Film Festival.
