It doesn't look like jet lag was getting to Britney Spears as the singer touched down on London soil yesterday and began her promotional appearances at the capital's radio stations.
The singer looked happy and relaxed as she arrived at Kiss FM's HQ wearing a red checked shirt, black leggings and suede fringed boots.
Making use of her time in London, Britney is also preparing to film the video for her new single Criminal.
Last week on Twitter, the singer wrote: "So excited to stop over in the UK before I start my European tour in a few weeks. Can't wait! I LOVE London, it's like my second home.. decided to shoot the Criminal video in the streets of merry old England when I get there..."
Britney is due to start her European tour in St Petersburg later this month, returning to London in October for her O2 Arena dates.
