The Femme Fatale singer gives photographers an eyeful of what she wore under her mini dress when leaving The Sanctum Soho Hotel.
Britney Spears has accidentally exposed her underwear in a recent outing. The Blonde beauty flashed pink lace panties to the papparazzi when she climbed into her car after leaving The Sanctum Soho Hotel in London.
The "I Wanna Go" singer was with her beau Jason Trawick that day. The popstar donned a tight-fitting lime green mini dress, while Jason opted for a plaid shirt and jeans. She wore a big rock, similar to the one she had when dropping by BBC Radio 1 a day earlier.
The jewel previously reignited persistent engagement rumors, but Jason quickly denied it. He told Access Hollywood's Billy Bush on Friday that he and Britney are not engaged.
Britney was in town to promote the upcoming European leg of her "Femme Fatale" tour. She's going to kick off the jaunt on September 22 at Ice Palace in Saint Petersburg, Russia with Joe Jonas opening for her in ten selected dates.
