Kevin Federline banned wife Britney Spears from his recent Las Vegas concert!

The 'Toxic' singer - who has a son, Sean Preston, with 28-year-old
Federline - is said to have been devastated after he broke the news to her
on a dinner date at plush Las Vegas restaurant Nero.

One onlooker said: "It was a full-blown war of words. It was a very bad
night for Britney.

"Kevin didn't want Britney overshadowing him on the red carpet. Britney fled
the restaurant and raced up to her suite alone, boycotting his performance."
Later that night, a dishevelled Federline joined family and friends at Vegas
' Pure nightclub to be introduced to the waiting crowd by Paris Hilton's
mother Kathy, without Britney.
