Lady GaGa arrives at fellow singer Mika's house, and wears a pair of thigh length lace-up boots in London, England.

The 23-year-old singer might have felt a draft, as her backside got up and personal with photographers. In the UK, Lady GaGa's Pokerface, held on to the third slot with Pussycat Dolls (Jai Ho!) and Ciara/Justin Timberlake in 4th and 5th place respectively.
