Britney is bursting out of her bra!

After her split from Kevin Federline pop princess Britney Spears is perhaps ready to show off her booty and let her hair down in skimpy outfits, that leave little to the imagination.

The 'Toxic' singer nearly bared all when out partying with Paris Hilton. Not only her bra but her fashion sense appeared to have deserted Britney Spears once more as she stepped out in this eye-popping outfit together pal Paris Hilton.

The green skimpy frock bore a striking resemblance to a fig leaf and covered little more than the real thing.

"It was a shocking outfit. No one could take their eyes off it - for all the wrong reasons. It was more trailer trash than pop princess.

She looked as if she would burst out of it at any moment and certainly wasn't wearing a bra with it," an onlooker was quoted by the Daily Mail, as saying.

"I am not even sure she managed to keep everything inside the dress all night. She certainly seems to be telling Kevin she is back on the market," he added.

Since announcing the split earlier this month, twice-married Miss Spears has sported a series of increasingly revealing outfits.
