Britney Spears arrived in the UK last week ahead of her European tour. Using Twitter, she revealed an extra surprise for her UK fans.

The 'Toxic' singer announced that she would be filming the video for 'Criminal', the fourth single from her 'Femme Fatale' album, in London:

"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."

A number of photos from this exciting video shoot have been released and it shows the 'Femme Fatale' clutching a hand gun as she and her real-life boyfriend, Jason Trawick, run out of a grocery store.

The photos show the singer laughing and giggling as she films this very interesting video, directed by Chris Marrs Piliero, who worked with Britney on her last video for 'I Wanna Go'. You can check out a series of pictures from the shoot below.

The 29-year-old singer is due to begin the European leg of her tour on September 22 in St. Petersburg, Russia but before then, she will be doing promotional work in the UK.
