Britney Spears hubby Kevin Federline may just have nailed his own coffin after he not only begged the singer for a reconciliation, but also asked her to return his 100,000 pound Ferrari. Federline followed the singer to Las Vegas where she was to attend the Billboard Awards, and reportedly begged her forgiveness for bringing home a druggie friend. However, Kevin managed to spoil the effect of his pleadings by asking Britney if she could return his beloved car to him. “He’s been calling all the time asking for forgiveness, saying he wants to be together as a family. He angered Britney by asking for his car but backed off when she got mad and went out with pals,” The Sun quoted a source, as saying. According to the source, even though Britney is apparently fed up with her husband’s partying and drinking, she is still devastated by the split and may still agree to give her rocky marriage another chance for the sake of the couple’s two month old son Sean Preston. “Although Britney has been partying with pals, deep down she’s devastated by the split. She’s so young and already has one failed marriage, not to mention the baby with Kevin. That’s why she may take him back,” the source added.
