BSPEARSKAB032607_18.jpgBritney Spears BSPEARSKAB032607_25.jpgWith all the time she's been spending at Millennium Dance Studio recently (three practice sessions in four days!), we're starting to wonder about when - or if - Britney's been seeing her babies lately! After all, Kevin's been pretty adamant about retaining custody over Sean and Jayden despite of Britney's successful completion of Promises' recovery program, and thus far the formerly blonde bombshell has only gotten a few limited opportunities to see her children. We did our best to inquire after the state of Britney's relationship with her kids as she made her way out of Millennium yesterday, but she didn't have a response - could she have just been tired? Unable to hear our questions over everyone else's? Or might we have touched on a raw nerve?
