Britney Spears was filmed having sex with a stranger she met on vacation, it has been claimed.
The 28-year-old unnamed man met the 'Toxic' singer while holidaying in Hawaii last June and secretly recorded them having sex in a bungalow at the Four Seasons hotel on the Kona-Kohala Coast.
He claims he has not sold the tape yet because he is embarrassed by his own performance.
The man told In Touch Weekly magazine: "It was just normal, we didn't do anything crazy. It was a little disappointing. It lasted for about 25 minutes and then we passed out."
He claims he met Britney, 25, in a bar at 1am on June 7 2007 and they went back to her room to "party" before "hooking up".
Meanwhile, the singer's close friend Sam Lufti has revealed she is "very optimistic" of getting her children back.
Britney - who was ordered by a judge to hand over sons, two-year-old Sean Preston and one-year-old Jayden James, to ex-husband Kevin Federline on Monday (01.10.07) - now has her legal affairs in order ahead of today's custody hearing (03.10.07).
Lufti told People magazine: "Kevin's custody is only temporary.
"We signed all the necessary documents that she needed to get done and Britney is in a good mood, no problems, very optimistic.
"Scheduling conflicts and errors in communication led her to believe that her deadline was later this week rather than Monday."
The California Department of Motor Vehicles also revealed yesterday (02.10.07) that Britney has been issued an interim driving licence.
Mike Marando of the DMV said: "She has fulfilled her requirements for a California driver's licence. She took and passed a written test in April. She will be issued a formal licence in the mail soon."
Last month, the singer was charged with misdemeanour driving without a valid California licence and hit-and-run after she hit another vehicle in a car park on August 6 and left the scene of the accident.
Los Angeles Superior Court Commissioner Scott M. Gordon, who is overseeing her custody case, ordered her to prove she was a legal driver.
Britney Spears: Sex tape threats

The Birmingham-born photographer is said to have taken a break from work and gone into hiding after revealing that he has been harassed by the singer's fans.
Mr Ghalib also claimed that he was stabbed in the arm in April as irate fans vented their fury over his relationship with the 26-year-old singer.
The video is alleged to feature Spears performing a striptease while wearing a pink wig during a trip the couple took to Mexico.
Britney Spears is So Sexy
A video of Britney Spears humping a one-night stand in Hawaii has the internet screaming today. A Britney Spears sex tape?
That is the claim anyway, although all that has been produced is this still shot above. And we don’t even think that is really her, much less that Britney Spears has a sex tape.
But if you are to believe it, a 28-year old bar trash kept a hidden camera in his hotel room while humping Spears in 2006 while she was on vacation in Hawaii. He claims that he has not released it yet because his sexual performance was substandard. All of this shown to In Touch magazine according to reports. The film will be worth a lot of money.
“It was just normal sex, we didn’t do anything crazy. It was a little disappointing. It lasted for about 25 minutes and then we passed out.”
That is pathetic. Guys who release sex tapes are creeps regardless of their sexual performance in bed. Guy who are bad in bed are creeps too. Smack them all.
Meanwhile, enjoy the Britney Spears sex tape hoax in all it’s glory. We advise that you not waste your time watching this video, particularly our friends.
Spears Sex Shocker Revealed by Federline Friend
HOLLYWOOD - Britney Spears' divorce battle could spark new rumors about the pop star's sexuality--if her estranged husband goes public with party gossip.Rap music producer Omar 'Iceman' Sharif, who is one of Kevin Federline's confidants, has gone public with reports about Spears' wild secret life, claiming the “Toxic” singer staged same sex parties at the mansion she shared with his pal.
Sharif tells In Touch magazine, "Britney was into threesomes and girls," adding the pop star would often invite a bunch of girlfriends over to the couple's house to party.
This comes years after bisexual porn queen Jenna Jameson revealed she and Spears had a special connection after the pop star told a mutual friend she was a fan of the actress' steamy movies.
Jameson revealed Spears invited her to the opening of her Nyla restaurant, but her handlers kept her away from the pop star.
One source tells In Touch that Federline plans to use details of his estranged wife's sexploits if his custody battle over their sons, Jayden James and Sean Preston, turns ugly.
The insider tells the publication, "He wants to show that she's not such an angel after all."
