Britney Spears' apparent ex-boyfriend, photographer Adnan Ghalib, reportedly told British magazine Heat he has a sex tape of himself with the pop star — but a source close to Spears denied it.

“There is such a tape,” Ghalib tells Heat, according to the U.K.'s Sun. “But I won’t discuss prices for hypothetical inquiries. Unless there is a locked-in deal, I will go no further. I am not interested in selling out any other details about Britney.”

A source tells The Sun that the two-hour X-rated footage features Britney naked wearing just a pink wig and was allegedly shot in Mexico. (Ghalib and Spears went to Mexico together in January, right before her breakdown.)

But a source close to Spears disputed the report.

"The story is completely false," the source told E! News.

Meanwhile, Spears' attorney has asked a judge to delay the singer's upcoming trial on a misdemeanor charge for driving without a valid license.

Attorney J. Michael Flanagan filed a petition in Los Angeles Superior Court on Monday seeking a stay in the criminal case. Flanagan also wants an appellate judge to order the judge overseeing the case to grant Spears' motion to dismiss.

Flanagan has twice requested a dismissal of the case, saying that Spears should be allowed to pay a $10 fine and not face a criminal trial.

The 26-year-old singer is scheduled to go on trial in October on a single misdemeanor charge that she did not have a valid California license when she hit a parked car in August 2007 and left the scene.

Flanagan also argues in Monday's filings that Spears is unable to meaningfully participate in her defense because of her conservatorship. Since February, her father has controlled the singer's personal and financial affairs.

Also Monday, the pop star told a New York radio station that her clip "Piece of Me" leaves room for improvement — despite winning three MTV Video Music Awards earlier this month.

"It's a cool video, but I think by far I've done videos that are way better," the singer said in an interview with top 40 radio station Z100. "So I was really shocked that ... it got the award."

Spears called her triple victory "inspiring, though, because now going forward with the videos that I'm doing now, I can really go there and do something crazy and see what happens."

Spears, whose new album "Circus" drops Dec. 2, plans a possible world tour next year.
