Shockingly, Spears replied that she could not care less for that, the source claims.
"When the subject of her boys' custody came up, one of the girls told Britney, "Don't worry, you'll get your kids back.' Britney replied: 'I don't give a s— anymore. I never wanted them in the first place," the New York Daily News quoted the source, as telling OK Magazine.
The 25-year-old, who had to hand over her sons to hubby Kevin Federline after a court ruling, reportedly dashed to party at the posh Peninsula Hotel just hours after she handed over the boys to K-Fed.
Apparently, Spears was also in a mood for revelry the night before the morning she had visitation with her kids, which she missed.
Star magazine reports that Spears has been frequently visiting hotels since that's the place she meets her drug dealer, an unidentified brunette.
