Spears Personal Life May Interfere with Smash Record!!!

Rapper/producer Timbaland predicts Britney Spears' comeback single will be an international smash - as long as she can straighten out her family life.

Timbaland admits he'd love the troubled pop superstar's upcoming track Gimme More to conquer the charts, but worries her custody battle with ex-husband Kevin Federline over their two children may get in the way.

Speaking on Ryan Seacrest's U.S. radio show on Kiis FM on Friday, he said, "I would love Britney to have a smash, it would be the greatest comeback ever. "I think it would be phenomenal, but I think she's got to be connected with her family. She can't do it alone."
