Washington, July 19 : Britney Spears will have to pay ex-husband Kevin Federline 20,000 dollars a month in child support, following the latter's win in the custody battle, it has emerged.
The custody settlement saw Federline retaining sole custody of the couple's two sons.
Federline's lawyer, Mark Vincent Kaplan, also demanded and received 250,000 dollars for his work on the case, a source said.
"All Britney was seeking was a formalization of her increased visitation that she's obtained over recent weeks, and the additional overnight," People quoted a source, as saying.
"She won both of those requests," the source added.
Spears, who is represented by lawyer Laura Wasser, currently sees her sons twice a week with one overnight.
The source added that the fallen pop princess will get an additional overnight by year's end, barring any setbacks.
