Britney Spears reportedly had a fit when her ex Justin Timberlake didn’t want to work on new music together. A source tells the National Enquirer, “Britney desperately wanted Justin to sing with her, and weeks ago she asked him to record a duet for her latest CD. But Justin wouldn’t make a commitment, even though they both record for Jive records.”

The insider claims that Britney “pitched a god-awful fit” and threw a “temper tantrum that would put a 2-year-old to shame.” Another source has come forward to tell GossipCop.com that the tantrum story is “not true.”
