Britney's Mystery Date?

Just a week after filing for divorce from her husband of two years, Kevin Federline, Britney Spears was seen having dinner with her son, Sean Preston, and a mystery man.

But despite reports of a new romance, the “mystery man” is none other than Brit's brother.

As Britney bounces back, we've discovered how Spears reached her breaking point in her marriage to K-Fed.

Us Weekly reports that Spears finally snapped after Federline sent her a handwritten letter blasting her for their problems.

“He blamed her for all of their problems, and that was when she said she had enough,” dished the magazine's Katrina Szish.

The magazine also revealed that Britney's mom, Lynne, and the star's divorce attorney held an intervention demanding Britney drop kick K-Fed out of Malibu and out of her life.

Now, Us Weekly also reports that the pop princess' former flame, Justin Timberlake, may write a song for her comeback album as part of Britney's dramatic makeover.

And speaking of Brit's magical transformation, her hot new look is causing some to speculate.

Even Us Weekly suspects Ms. Britney may have had a little work done.

“Experts are telling us she may have had breast augmentation,” Szish said.

But then again, it could also be the side effect of just giving birth to son Jayden James; Britney's rep declined to comment.
