Kevin Federline feared overshadowing by Wife Britney Spears
Britney Spears apparently didn't show up to support husband Kevin Federline at his pre-album launch promotional gig in Las Vegas at the weekend because he ordered her to stay in the background.
Federline told Britney over dinner at the Nero restaurant in Caesar's Palace.
An onlooker reported: "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."
Kevin continued with the show anyway, performing a couple of songs from his forthcoming album "Playing with Fire" for friends and fans at the Pure nightclub in the famous casino.
