"I’m not sure if she’ll come to Cardiff where the show is shot so I’m nagging the BBC to fund a Hollywood special," he is quoted by the Daily Star as saying.

"I’d love Britney to do it - it would be so much fun," he added.

Brit would play a race of cloned creatures who all look identical, reports the paper.

The appearance could revive the pop princess’ career, which has been dogged with problems recently.

Yesterday it was reported that Brit actor Sir Derek Jacobi would play a man who saves Earth in the new series of Doctor Who.

The third series, which stars 35-year-old David Tennant as the Doctor, starts in the spring.

Britney denies romance - Jan 23 2007
It looks like Britney Spears’s rumoured relationship with model Isaac Cohen may be over already, after the pop princess told photographers that they’re "not together".

Snappers for photo agency X17 captured footage of the singer denying she was in a relationship with Isaac when she made a pit-stop at Santa Monica’s Coffee Bean & Tea Leaf cafe.

Despite having been photographed getting cosy with the 25-year-old model in LA and Las Vegas over the past couple of weeks, Britney told the throng of photographers: "Me and Isaac are not together by the way."

Asked by the lens-men whether it was "really over", Britney, 25, reportedly replied: "Yes."

Earlier in the day, the mum-of-two was caught on camera giggling with two female companions as she flicked through a copy of Us Weekly magazine bearing the cover story "Brit’s New Man".

The pair were last spotted together on Thursday, apparently picking up goodies from a string of LA boutiques.

Britney not pregnant, says rep - Jan 18 2007
Britney’s rep, Larry Rudolph, has denied US media reports suggesting that the singer may be expecting her third child.

"Britney is not pregnant," Larry told Us Weekly, calling a story in a rival magazine which suggested that her rumoured New Year’s Eve collapse may indicate a pregnancy "absurd".

Larry said he believes the pregnancy rumour stemmed from an incident last week in which Britney’s new beau, Isaac Cohen, was photographed with the singer sporting brown goo on his clothing.

Contrary to suggestions that Brit may have suffered an unexpected bout of morning sickness, Isaac reportedly told the photographers that he’d simply had an accident with a jar of peanut butter and hadn’t had chance to clean up the mess.

"Because Isaac didn’t lick the peanut butter off his fingers, someone decided that it must not be peanut butter, but must instead be Britney’s vomit," Larry added, calling the claims "ridiculous".

According to Us Weekly’s sources, Britney has in fact been spending time in an LA recording studio with none other than super-producer Pharrell Williams, working on her hotly anticipated new album.

Britney’s lavish date - Jan 16 2007
Clearly out to impress her new man, Britney Spears treated Isaac Cohen to a lavish night in the Fantasy Tower suite at The Palms in Las Vegas on Saturday night, according to US reports.

People magazine reports that Britney and her new man spent the night at the tower’s 40,000 US dollar-a-night, two-story Hugh Hefner Sky Villa on Saturday, which features a Jacuzzi pool, fully-stocked bar, a glass elevator and an 8ft rotating bed.

"They seem very happy together," a source who spotted the couple told the magazine, though hotel officials offered no comment.
