Pussycat Dolls Picture 2251038

Pic caption: Joanne Stefani Germanotta aka Lady GaGa arrives at Heathrow airport early this morning, following her week long stay in London. She is due to begin her stint as a support act on the Pussycat Dolls tour this evening, which starts in Aberdeen. GaGa opted for a biker girl look, as she teamed leather gloves, a leather hat and a leather jacket with black leggings, a black top and killer Chanel heels. She was reluctant to be photographed at first, but soon warmed to the photographers, who asked if she was feeling tired, having only had a few hours sleep. London, England - 18.01.09
