Fears are growing for the safety of the glamour model stepdaughter of ex-England star Paul Gascoigne after she went missing from a Spanish music festival.

Radio silence: Bianca has not used Twitter or Facebook in a week

Bianca Gascoigne, 22, was at Benicassim last weekend when it was hit by storms on Friday and evacuated.

She was taken with her friends to a sports hall to sit out the hurricane but her mother Sheryl is getting increasingly concerned as she has not heard from her daughter since.

A spokeswoman for her agent Jonathan Lipman said they had “absolutely no idea where she is”. They said: “We knew it had to be serious when her mother called the office. We've been trying to get hold of her but have had no luck. We know that her battery is dead... but we've no way of getting in touch with her.

“The parents of one of her friends she went to Benicassim with live in Spain, so she could have gone there, but if she did, why did she not call her family to let them know she was safe?”

Bianca has also not updated her Twitter page since 13 July, when she said “Bianca Gascoigne is so... happy! cant wait for weds going BENNICASSIM... four day festival in Spain oh yeah! who else is going?”

She's also not been on Facebook since she left for the festival, which has raised even more concerns among her family.

The spokeswoman added: “She is a Facebook addict so it's worrying that she's not been on since July 15. We're going to try and get hold of her new boyfriend on there and see if he knows anything.”

She also said Bianca didn't show up for an important project that had “been planned for ages”.

“We're all hoping she's fine and has just gone off partying somewhere. It's not unlike her to be out of service... and not contact anyone for a couple of days. But it's been over a week now so obviously we are concerned.”
