Britney Spears has pulled out of plans to re-record Marvin Gaye and Tammi Terrell’s Motown classic ‘You’re All I Need To Get By” with ex-boyfriend Justin Timberlake.

A source told the New York Post newspaper: “Timbaland set aside a week out of his crazy schedule to do this - and then, just before she was supposed to fly out, Britney abruptly cancelled the session and refused to do the song.

“It’s crazy. She’s looking for a comeback, and this would have not only been a huge hit, but something she could have opened the MTV Video Awards with it and really blown everyone away.”
