She’s working hard to ensure she’s at peak fitness throughout her Las Vegas residency.
But Britney Spears opted for an unusual take on workout gear as she hit the gym in a new social media video on Tuesday night.
The pop princess, 35, looked incredible as she flaunted her washboard abs in a barely-there crochet string bikini top while working up a sweat in a gruelling session.
The Hit Me Baby One More Time hitmaker teamed her skimpy swimwear with comfortable black jogging bottoms.
Britney swapped her glitzy towering heels for practical trainers as she trained in the gym with weights.
Wearing her golden locks in a high ponytail, the mother-of-two showed off her pretty features when training alongside a blonde friend.
She wrote on Instagram: ‘Training keeps me motivated and inspired… but I’d rather be dancing.’
Britney’s legion of 15.8million social media followers flooded the Instagram video post with compliments, praising the songstress for having the ‘perfect body’.
One admirer said: ‘Only Britney can workout in a bikini top and it be completely okay.’
Another added: ‘Omg!!! perfect body! I’m proud for you.’
A fan wrote: ‘Omg hit me baby one more time.’
No doubt the blonde has been picking up some tips for the gym from her personal trainer and model beau Sam Asghari, 22.
The couple have been dating for five months after they struck up a romance on the set of her music video The Slumber Party.
Britney is a doting mother to her two sons Sean Preston, 11, and Jayden James, 10, with her ex-husband, dancer Kevin Federline, 39.
The couple tied the knot in September 2004 in Studio City, California, just five months after they started dating.
Britney and Kevin’s divorce was finalised in 2007 after three years of marriage.
In addition to her Las Vegas residency, which has run on and off since 2013, Britney recently announced that she would be performing abroad for the first time since 2011.
The singer will visit Israel, Japan and The Philippines, with more dates expected to be announced in the future.
