Tameka Raymond, mother of Usher's 2 children, from a short 2 year marriage, has filed papers in the state of Georgia to have their joint custody of their children taken away from Usher, immediately!  According to the docs, filed by Tameka, she claims that Usher has failed to obtain her permission to travel outside the state with the kids, though he's legally obligated to do so. Tameka also claims Usher is required, but failed to: 1. get her approval before hiring nannies 2.  give her first shot to watch the kids when he's away for more than 8 hours 3. allow her to take the kids for 2-weeks in the summer of 2011 4.  let her have custody of the kids during Christmas break 2010. She also says that Usher owes over $34,000 for pass due payments of $5,000 a month for nannies, and he closed her Saks 5th Avenue credit card! Tameka is requesting for more child support, due to the success of Usher's career since the divorce. A hearing will be held on Wednesday.
