Kevin Federline has been showing his soon-to-be-ex-wife Britney Spears some support by bringing sons Sean and Jayden to visit their troubled mum in rehab. According to People magazine, 1-year-old Sean and 5-month-old Jayden visited Britney over the weekend. Kevin and Britney currently have joint custody of the tots, though friends fear Britney's recent breakdown may not do her demand for sole custody any favours. A source close to Federline said, "The kids are his No. 1 priority. He's so stressed out right now. He only wants the best for Britney and the kids." It was Kevin's second visit to the clinic - he also went to see Britney on his own on Friday. |
