Britney Spears looked a little more subdued than usual arriving at the Beverly Hills Hotel for her first co-parenting class with Kevin yesterday afternoon. Who has parenting class at the Beverly Hills Hotel? The Spears Federlines, of course! The ex-couple's next custody hearing isn't until tomorrow, but before then they are to have finished three of their six sessions (in which they learn how to be polite to each other, use "I" phrases, etc) and Brit has to have three individual sessions, too. Sounds like today is going be busy for both Britney and her lawyer, who told TMZ that this morning he plans to plead not guilty to Brit's misdemeanor charge for driving without a valid license. Never just a quiet Thursday for her. Just like all things Britney, this week has potential to end with some drama.
