An array of fire-breathers, male and female dancers and circus performers welcomed the popstar to the Planet Hollywood Resort and Casino on Tuesday (3 December).
At the welcome ceremony, Britney celebrated the release of her eighth studio album, Britney Jean, and was given a large bouquet of flowers, after signing autographs for fans who were waiting to catch a glimpse of her.
Britney, who celebrated her birthday on Monday (2 December), was beaming as she arrived in a chic black cocktail dress adorned with sliver embellishments. She teamed her LBD with some silver platform heels.
According to reports, a block of the Vegas strip was shut down to make way for the 32-year-old's arrival. That's some entrance!
Speaking to the crowds, Britney said: "I already feel like home here at Planet Hollywood. It's so nice to celebrate with this incredible welcome.
"I'm so excited for everyone to experience the new show. Now it's just a few weeks."
Britney also updated fans on Twitter with her celebrations, saying: "In Vegas! Celebrating #BritneyJean & #PieceOfMe with my new Vegas family."
Although the celebrations were lavish, it was only a short stop for the 'Toxic' singer, as she had to catch a flight back to Los Angeles! There's just no stopping her!
Britney's grand premiere of her 'Britney: Piece of Me' residency will be on 27 December, where she will be contracted to perform 50 shows a year in 2014 and 2015.
