Lindsay Lohan’s father Michael has challenged Britney Spears’ ex-husband Kevin Federline to a boxing match, to raise money for charity.

Lohan Snr, a former convict, wants the bout to raise money for a cancer charity based near his Long Island, New York home.

Although Federline has yet to be approached, Lohan is already planning his training regime.

He tells Ok! magazine, “Everyone wants me to fight K-fed because he’s a notorious celebrity dad and so am I. It’s for charity.”

“It’s serious boxing. You have to go get a trainer. I have to register with the Mature Boxing Association.”

And if Federline says no - he’ll search out another willing celebrity opponent: “I don’t care who it is; it’s for charity. I’ve been beaten up by the press, so I don’t care if I get a few shots by a kid half my age.” Lohan is even trying to pair up his girlfriend Erin in a fight, adding, “They’re trying to match her up with Debbie Gibson.”

Justin Timberlake has denied reports he will team up with ex-girlfriend Britney Spears to collaborate on a song.

Spears is currently recording the follow-up to her 2007 album “Blackout,” and her new album was reported to feature a duet with the “SexyBack” singer, her former boyfriend.

But Timberlake’s spokesman has denied the collaboration, insisting he “is not scheduled to be in the recording studio with Britney.”

Spears and Timberlake split up in 2002 after dating for four years. The former boy-band member is currently romancing Hollywood actress Jessica Biel.

Britney Spears says her sixth album will be out within nine months as the U.S. pop star seeks to rebound from troubling behavior and hospital stints for psychiatric evaluations.

In an interview with OK! magazine released on Wednesday, the 26-year-old says she has written more for the new album than her previous five studio albums, and describes it as having an “urban” feel.

“I’m writing every day, right here at the piano,” said Spears, one of the world’s most successful pop stars of the early 2000s. Her last album, “Blackout,” debuted at No. 2 on Billboard 200 last November, but quickly slid down the chart.

Spears has given few interviews in recent years as her life spiraled out of control and she lost custody of her two sons.

Over the past 18 months she has been involved in an ugly divorce from Kevin Federline, entered rehab treatment several times, and exhibited erratic behavior like shaving her head and attacking a photographer’s car with an umbrella.

But in the past six months, her father Jamie Spears has taken over management of her affairs and she was also mentioned as a possible Emmy award nominee for guest appearances on U.S. TV series “How I Met Your Mother.”

When asked by OK! if she would like to do more acting, Spears said: “I’d love to, if I can find the right movie.”

“Actually, I have a part that just came up. We’re just trying to work it out with my schedule, with the children,” she said.

A court recently extended Jamie Spears control over his daughter’s affairs, which he shares with Los Angeles attorney Andrew Wallet, until the end of 2008.

Britney Spears, who is looking increasingly glamorous and cheerful every day, left us drooling when she made a five minute stop at Lisa Kline on Robertson Blvd in Los Angeles on Saturday, August 9. What pop wreck? We saw a ravishing blond pop star yesterday!

The 26-year-old yummy mummy showed her well toned body in green hot pants and white tee. She accessorized with large shades, danglers, bangles and, most of all, a pendant necklace that read Jayden Preston. Her flip flops added to the casual but powerful allure.

The video shows Britney in a comical and improvised question and answer session with VMA host, Russell Brand. It also features LL Cool J, FNMTV host/ Fall Out Boy bassist Pete Wentz, and a 9,000 pound elephant!

Britney’s fans are hoping that she will perform again at the awards this year, for no other reason than to make up for her disastrous performance last year!

Despite 17 nominations Britney has yet to walk away with a VMA. This year she has been nominated under two categories for the song Piece of Me from her last album Blackout : Best Pop Video and Best Female Video.

MTV’s Video Music Awards 2008 will air live from the legendary Paramount Pictures Studios in Hollywood on September 7 at 9 pm. They will be hosted by British comedian Russell Brand and include performances by nominees Lil Wayne and the Jonas Brothers.

Lindsay Lohan said Friday that police have no business getting involved in her personal life, a day after the police chief explained that the paparazzi were no longer an issue — in part because the 22-year-old actress had evidently “gone gay.”

“Police chiefs shouldn’t get involved in everyone else’s business when it comes to their personal life. It’s inappropriate,” Lohan said in a video shot by paparazzi Friday and posted on TMZ.com. In the footage, Lohan and gal pal Samantha Ronson are trekking through the Los Angeles Airport on their way to catch a flight to Chicago.

The day before, Chief William Bratton said the paparazzi have become less of a problem thanks to Britney Spears, Paris Hilton and Lohan leading more moderate lifestyles.

“If you notice, since Britney started wearing clothes and behaving; Paris is out of town not bothering anybody anymore, thank God, and evidently, Lindsay Lohan has gone gay, we don’t seem to have much of an issue,” he told KNBC-TV.

Bratton was speaking about his refusal to participate in a meeting held by elected officials Thursday that was called to discuss new laws to curb problem paparazzi.

He called Los Angeles City Councilman Dennis Zine’s special session — which was attended by the likes of John Mayer, Eric Roberts and Milo Ventimiglia — “a complete waste of time.”

Bratton later called a news conference outside police headquarters to clarify his position on the paparazzi. When asked about the Lohan remark — which followed months of tabloid speculation that Lohan and Ronson, a DJ, are dating — Bratton said his sister is gay and he is a proponent of gay rights.
