Nicole Scherzinger goes bra-less in VERY low-cut leather frock as she hits the town in London

She spent her day on Wednesday buttoned up in a Greggs uniform as she visited a London branch of the bakery.

But Nicole Scherzinger cut a dramatically different figure later that evening.

The 35-year-old went bra-less in a very low-cut frock as she left restaurant The Arts Club in Mayfair after appearing on The Graham Norton Show.

The X Factor judge left little to the imagination in the revealing dress, which featured a leather bodice and see-through chiffon skirt, as well as a cutout at the waist.

It was clear Nicole wasn't wearing a bra as she displayed ample cleavage in the flimsy top.

The former Pussycat Doll wore her highlighted brown hair in glamorous waves over her shoulders and opted for black eyeliner and nude lipgloss.

The singer appeared to have had quite the fun night, giggling with her friends as she was escorted to her waiting car.

Once in the backseat, she showed off her long legs as her friend next to her was seen taking a picture of the photographers with her smartphone.

Nicole had apparently come from filming the Graham Norton Show earlier in the evening.

Meanwhile, Nicole cut quite a different figure earlier in the day as she spent time behind a counter at a Central London branch of Greiggs.

Nicole took the opportunity to sample a traditional sausage roll during some quality bonding time with her X Factor contestant Hannah.

She even put on a Greggs uniform and got stuck in as the 17-year-old showed her what life was like for her before the bright lights on the talent show.
