Britney Spears with a new blonde bob on David Letterman's showThe writing was reportedly on the wall for Britney Spears and Kevin Federline’s marriage last week after they were spotted arguing on Halloween then Kevin apparently skipped out on a last-ditch attempt dinner date.

According to the Sun, Britney and Kevin had a bitter row before before Kevin’s performance for the West Hollywood Halloween Carnival last Tuesday, which ended with Britney screaming at him “you’re useless - you’re a nobody”. After she stormed out, Kevin was spotted in kneeling and crying in the corner before having to take to the stage in front of a jeering and booing audience.

Britney was nowhere to be seen while he performed his song ‘Privilege’ but was later spotted at the after-show wearing a pink wig and oversized sunglasses.

The two are thought to have argued again on Thursday in New York but Britney dressed up in a sexy black dress to have a make-up dinner with her husband of two years - only for him to stand her up. Britney was spotted having a meal with her bodyguard instead but was reportedly visibly upset while eating.
