The 'Roar' singer was dressed to impress as she headed to the swanky Mayfair restaurant straight after filming an episode of The Graham Norton Show.
Gorgeous Katy showed off her incredible figure in a tight maxi dress, adorned with a pretty monochrome feather print.
She highlighted her waist with a skinny beaded belt, adding a leather biker jacket and heeled ankle boots.
Her jet black tresses were pinned back to one side and she accessorised with a statement gemstone ring.
But it's not just her floor-sweeping frock we're lusting after - we love her make-up too!
The songstress highlighted her piercing blue peepers with brown smoky eyeshadow and heaps of mascara. She added a dash of drama with berry red lipstick, highlighting her cheeks with a pop of peach blusher.
