For those who might doubt the fact that Britney Spears is back with a bang, just check out pictures of her performing at the iHeartRadio Music Festival in Las Vegas at the weekend.

The pop superstar, 34, looked truly sensational as she hit the stage at the prestigious music event, harking back to her early Noughties days with her ab-baring ensemble.

She wore the tiniest of outfits – bra-like crop top with a feather skirt and over-the-knee boots – and her blonde mane was typically Britney: We’re thinking Britney circa 2004-ish.

It was all sassy dance moves and typical Britney flair as she strutted her stuff, singing a selection of her biggest hits including Womanizer, Toxic and Stronger.

After wowing the audience at the T-Mobile Arena in the city, Britney took to Instagram to gush over the gig, which also saw her take to the stage with her Make Me collaborator G-Eazy.

After years of ups and downs, the Oops I Did It Again hitmaker has made a pretty remarkable return to the spotlight and is currently in the process of promoting her ninth studio album Glory.

She has also made Sin City her temporary home as she brings in the audiences with her Piece Of Me residency at the AXIS auditorium located in the Planet Hollywood Resort & Casino.
