Britney Spears’ husband Kevin Federline spent three nights at a friend’s place after they had a blazing row. The couple, who have been having problems since having their baby last month, were counselled back together by Britney’s mum Lynne. Kevin (27) has spent his time golfing, partying and talking on the phone since his child Sean Preston came home, leading the 23-year-old ‘Toxic’ singer to complain that she’s “raising two kids now”.
