Representatives for Britney Spears have confirmed that the 22-year-old singer is engaged to Kevin Federline, a back-up dancer on the singer's recently canceled Onyx Hotel tour. No wedding date has been reported. Federline, whose close monitoring of Spears as she recovers from knee surgery first sparked the rumors, recently slipped a two-carat diamond engagement ring on her finger, much to the displeasure of his pregnant ex-girlfriend, Shar Jackson, who has since taken to the tabloids with delicious quotes about the new couple. Spears, meanwhile, is rumored to be planning a more traditional wedding -- one quite dissimilar from her Vegas nuptials with childhood friend Jason Alexander back in January, which lasted all of 55 hours before being annulled. --Prepared by IMDb Staff

A woman who helped actress Angelina Jolie adopt her Cambodian son Maddox has pleaded guilty to visa fraud and money laundering. Lauryn Galindo, 53, of Hawaii and her sister in Seattle, Washington, Lynn Devin, received fees of $10,000 or more to arrange adoptions by US residents of children described as orphans - even though many still had parents, according to the documents. Devin - who pleaded guilty in December, but has not yet been sentenced - and Galindo have agreed to surrender all property associated with the crimes, including a home in Hawaii. The sisters operated an agency called Seattle International Adoptions, which paired hundreds of children from Cambodia with adoptive parents from 1997 to 2001, when suspicious US immigration authorities halted adoptions from the impoverished south-east Asian country. The adoption ring - which paid poor women as little as $100 (£ 55) for their children, according to an attorney - received a total of $93,700 (£52,055) for the adoptions cited in the case. Galindo could face up to 20 years in prison at a sentencing hearing set for September. Prosecutors have said the investigation will not change the status of children adopted through the Seattle adoption agency. Jolie adopted Maddox last year after meeting him in an orphanage in November 2001.
