Beyonce Knowles launched her first UK fashion collection during London Fashion Week on Saturday (17.09.11).

The singer-and-actress - who is expecting her first child with husband Jay-Z - and her mother Tina unveiled their House of Dereon collection at exclusive store Selfridges, where the pair paraded down the catwalk in hand-in-hand.

Star guests at the launch included Paloma Faith, Eliza Doolittle and Rosario Dawson.

However, one A-list celebrity who failed to attend was Beyonce's close friend Gwyneth Paltrow.

The 'Crazy In Love' hitmaker reportedly delayed the catwalk show for 45 minutes in the hope the Oscar-winning actress would turn up but eventually had to go ahead without her.

A source told The Sun newspaper: "Beyonce halted the whole thing because she thought Gwyneth was about to arrive.

"She kept calling her but she didn't show. People couldn't wait any longer and they had to get on with it. Beyonce wasn't angry. She was just disappointed."

However, Beyonce didn't let it upset her too much and was thrilled with how the show went.

An insider said: "It was Beyonce's first fashion show outside the US - and she was thrilled with it."
