Spears celebrates first anniversary of Las Vegas residency

Los Angeles: Pop star Britney Spears celebrated the first anniversary of her Las Vegas residency.

The 33-year-old mother of two performed her first 'Piece of Me' show in seven weeks to mark the occasion, and celebrated with her crew after the concert.

The singer also posted a video featuring her highlights from the past 12 months, including the inaugural Britney Day in Las Vegas on November 5.
"#PieceOfMe is 1 year old today! Thank you to everyone who has made this past year so special," she tweeted.

Earlier this year, Spears signed up to perform at Planet Hollywood for a further two years, meaning her run in the city is now set to conclude at the end of 2017.
