Nicole Scherzinger 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. Nicole wasn’t wearing a bra as she displayed ample cleavage in the short top. See the tasteful flicks in the gallery after the jump!
