Kevin Federline comforts Britney after an argumentKevin Federline comforts Britney after an argumentIt seems that poor Britney Spears has had a bit of a to-do of late with her husband Kevin Federline.

Kev is clearly coming to the realisation that if you date an international star... you have to behave yourself as there's really nowhere to hide.

According to the Daily Mirror, the 27-year-old dancer was seen getting a bit friendly with 'VIP escort' Vanessa Hulihan during a weekend away in Las Vegas with his mates.

Apparently, Kev was partying with Vanessa at Sin City's Pure club, and an onlooker told America's Us Magazine: "At one point she was sitting on his lap... he was sliding his hand between her thighs."

Britney, Kev and their new additionBritney and Kevin in happier modeEvidently, Britney had spotted this magazine report and when Kevin returned her arms were apparently far from open.

The Sun says that when he got back, Brit - who's rumoured to be pregnant - confronted her husband and burst into tears during a row.

After Kev left Brit's brother's house, alone, he was overheard by a photographer telling a friend: "She's kicked me out."

However, it seems that Britney saved most of her spleen to vent against the magazine - and others like it - writing on her website:

Dear False Tabloids,

As you read this letter, I bet you are asking yourself: Who? Who, me? Am I a false tabloid? Well, I don't know. But after this posting, I hope you are asking yourself a lot of questions. Your employees are a reflection of your magazine. Do you, Us Weekly, In Touch, Star and other desperate magazines want employees who are honest, or those who are liars? It seems to me that you'd prefer the latter. I'm really concerned about the people you hire to work at your companies. I'd like them to ask themselves the question, "What am I lying to myself about?" Is it that you are 50 pounds overweight? Is it that your children aren't making wise decisions? Or is it maybe that your husband or boyfriend is cheating on you? Until you face what is going on in your life, I guess you'll remain a false tabloid.

Britney

P.S. People Magazine is great in my book!
