Oops, I did it again: but this time via text message

The 24-year-old singer decided it was all over on Monday after a very tempestuous marriage and sent a message to Kevin's BlackBerry telling him exactly that.

The wannabe rapper, 27, was filming a segment for MuchMusic in Canada at the time. He interrupted the interview and stormed off, returning 30 minutes later visibly upset.

While the mother of two, who looks amazing after giving birth just eight weeks ago, was filing divorce papers at the Los Angeles superior court citing "irreconcilable differences", Kevin was gushing about his "supportive-wife" and how much he loved his family. The whole incident has been caught on video.

The news of the split broke a day after Britney appeared on the David Letterman show in America showing off her new toned figure and bobbed haircut. She didn't mention the break-up but there have been numerous reports since June that the marriage was in trouble.

Just last week the pop princess had a furious Halloween bust-up with K-Fed, and she was overheard screaming: "You're useless - you're nobody," at him at the nightclub launch of his own rap album.

Federline, her former backing dancer, was later seen crouched in a corner crying. He then spent last weekend in New York plugging his debut album, before heading to Canada on Monday.

The couple, who married in September 2004 after dating for three months, had arranged to meet in New York but Kevin checked into a separate hotel, leaving Britney with their two sons, Sean Preston, one, and two-month-old Jayden James.

She was later seen in tears as she exchanged angry words with her husband on her mobile phone. He is believed to have stood her up, preferring to hit the town with five friends instead.

This was the last straw for Britney, who has asked that the couples' assets -including "jewellery and other personal effects", and "earnings and accumulations from and after the date of separation" - are confirmed as "separate" property.

But she came out of hiding last night and embarked on a two-hour tour of New York's tourist attractions in a bid to show she is getting over the split.

When asked how she was coping with the divorce she replied: "I'm doing OK." She looked like she didn't have a care in the world as she went to the famous ice rink at the city's Rockefeller Center with her former manager Larry Rudolph.

Britney fired Mr Rudolph, who was responsible for making her a star, a few years ago but it looks as if he may have a hand in her new album Fears Within, which is due out next summer.

This will be Britney's second divorce. She wed childhood friend Jason Alexander in January 2004 in Las Vegas. The marriage was annulled two days later.

And he won't get half her fortune

Kevin federline can forget getting his hands on Britney's wealth. The singer is worth more than £65 million but most of that money is safe as the couple had a prenup agreement.

The £4 million Malibu mansion, currently home to Britney, and sometimes to Federline, will be divided 50/50.

Any gift worth more than $10,000 (£5,200) the couple have given each other will go back to the original purchaser.

This includes a custombuilt motorcycle Britney gave her husband for

Christmas two years ago. Even though he won't have access to her millions, Britney will still support him for a while. She has to pay Federline $30,000 (£15,700) a month for a year - half the time they were wed. This means that he will receive about £180,000.
