Pop diva Britney Spears reportedly had a make-or-break weekend with husband Kevin Federline in Hawaii - in a bid to save their marriage.

The singer, who is rumoured to be pregnant, and Kevin holed themselves up in Hawaii's exclusive Four Seasons hotel to try and sort out the problems in their relationship, celebrity portal Femalefirst reported.

Sources claim the couple - who married last September after a whirlwind romance - have been having blazing rows and are on the verge of separating.

One source told Britain's News of the World newspaper: "They just can't go on like this - there has just been row after row over the past few weeks.

"Both their families and all their friends have been getting involved and it has got out of hand. They have now been forced to go away by themselves to try to sort it out."
