As we pointed out earlier in the week, Britney Spears seems to be feeling better than ever and it shows! She has a sparkling career, loving relationship and two beautiful little boys. It doesn't hurt that she's currently in London either, enjoying the sights and partying it up with boyfriend Jason Trawick! We spotted the couple attending the launch party for her UK tour this Friday, and Britney looked truly great in a figure-hugging green and black mesh dress.
