It’s not often that we see Leona Lewis in London, but when she’s back we welcome her with open arms.

Yesterday the British singing sensation arrived at Waterstone’s book store in London to sign copies of her book title “Dreams”.

She looked very smart wearing a black Alexander McQueen Pre-Fall 2009 dress with a key-hole neckline and puffy short-sleeves.

The dress was paired with L.A.M.B multi button shoes, whilst her honey coloured hair was swept back into a loose ponytail with a few pieces framing her face.

Unfortunately the event ended badly when a crazy fan punched her in the face.

I hope she is doing well.
