Britney Spears Flaunts Curves in Skin-Tight Dress at UK Launch Party (PHOTOS)

Across the pond, Britney Spears is taking over. To prepare for the kick off the European leg of her Femme Fatale tour, Brit threw a Tour Launch Party in London for the crew and her back-up dancers.

The “I Wanna Go” singer was all smiles as she arrived at the Sanctum Soho holding hands with boyfriend Jason Trawick. She looked fab in a black and green curve-hugging dress that showed off her toned legs. Brit is definitely looking better than ever! 

The 29-year-old singer was seen outside KIIS FM studios in London on Thursday, and was smiling ear to ear as the paps snapped away. Looking cute in a plaid red top, Brit, who usually wear her hair down, pulled back her blonde locks.

The pop queen was spotted in London sporting a massive rock on her ring finger — could she and Jason finally be taking the plunge after months of rumor.
