She is definitely bringing sexy back.

Britney Spears vamped it up in seriously steamy costumes for her Piece Of Me residency at the Axis Theatre in Planet Hollywood Hotel and Casino in Las Vegas.

The 33-year-old, who was back in Sin City after a break, donned one revealing outfit after another for the 90-minute set on Wednesday evening.

Singing against a massive backdrop of screens to create stunning visuals, the blonde favoured little black bustieres that showed off her cleavage with fishnet stockings and high-heeled booties that made the most of her muscled legs.

She also dared to bare her curves in see-through, sheer body suits with a few carefully placed sequins preserving her modesty.

Adding a bit of 50 Shades Of Grey naughtiness, she carried a whip for part of the performance and bent over a chair presenting her derriere to the audience.

In one massive Vegas-style set piece, the mother-of-two rises high above the stage as an angel with a long white dress trailing down.

Britney is eighteen months into her residency at Axis, which kicked off on December 27, 2013 and originally committed her to play 50 shows a year for two years for a reported $30 million.

However, the show has been such a hit the Toxic star confirmed on Good Morning Britain that she had agreed to extend her contract with Planet Hollywood for two more years.

Piece Of Me had earned a reported $46 million in the 4,600-seat arena up until the end of March.

Meanwhile, the busy star - who has two sons, Jayden, eight and Sean, nine - will debut her much anticipated single Pretty Girls, her collaboration with Iggy Azalea, at the Billboard Music Awards on May 17.

Her previous single, Alien, peaked at number eight on the Hot 100 charts last July.
