Avril Lavigne mayfair hotel musician singer MrPaparazzi

Avril Lavigne - seen smiling above at the Mayfair Hotel - is still in London promoting her latest album, Goodbye Lullaby.

The "What The Hell" singer is both performing and presenting at the BRIT Awards tonight, and Avril is worried about tripping: "I am presenting an award and I am wearing a dress and heels. I will be trying not to fall! I really would like to wear these boots with my dress," she says.

The event will see live performances from Rihanna, Adele, Cee Lo and Arcade Fire.
