Britney had a full day of work and more work yesterday, first at the Millennium Dance Studio, then for a recording a session with her one-time paramour, JR Rotem! (Video coming soon.) Maybe that's what had Brit in such a great mood? There is one thing that seemed to be bothering Britney yesterday, her wig! You can see part of her short hair peeking through (oh how I wish she'd just show us already!) the wig, which must be incredibly hot and uncomfortable in the summer sun.
