Britney Spears' is all over the place on tour right now, but she is still seeing her kids.  Brit is even showing them how fun the spotlight can be.  Monday night, she tweeted a picture of herself and her older son, Sean Preston, onstage during her Femme Fatale tour in Budapest, Hungary on September 30.  We have the video and it shows proud mommy Britney leading Sean out by the hand during the finale of "'Til the World Ends," as confetti falls everywhere.  After Britney thanks the crowd, she and Sean wave goodbye and slowly disappear down into the stage.

Britney's next show on the current leg of her Femme Fatale tour is a stop in Amneville, France on Wednesday.   It wraps in Puerto Rico December 10.
