She’s been hard at work on her Revival tour, which kicked off last month.

And Selena Gomez was joined by pop star pal Joe Jonas and his band DNCE as she took to the stage in Louisville, Kentucky, on Wednesday night.

The 23-year-old starlet looked incredible as she rocked out, showcasing her incredible figure in a rather daring leotard and completely sheer body stocking.

With the diamante bodysuit glittering in the stage lights, she removed the floor length peplum outer dress during the show, revealing a form-fitting cutaway bustier that made the most of her ample assets and pert posterior.

The full length sleeves and high neck of the sheer fabric contrasted starkly with the raunchy undergarment’s minimal coverage.

The pretty star paired her striking outfit with black leather ankle boots which she used to full effect as she rocked her way through the set.

With her lustrous long hair billowing out behind her as she danced, the lights enhanced her honeyed highlights to full effect.

With her make-up matte and understated, nude lips and smokey eyes were the main focus of her look.

Former boy bander Joe and his band DNCE added their own rock vibe to the show, with the 26-year-old singer grabbing his own piece of the limelight in a bright white denim jacket and tie dye black and white distressed jeans.

Bright white trainers gave him freedom to jump around, and fitted the bill in his black and white colour palette.

With his jet black hair slicked back, he dance around the stage as he sang, giving it his all as he performed along his bandmates.

Jonas formed DNCE last year with musicians Jack Lawless, Cole Whittle, and JinJoo Lee.

In a black leather skirt and crop top combo, JinJoo rocked her own vampy look as she sang and played electric guitar, with her neon pink hair adding a punk vibe to her ensemble.

Their debut hit Cake By The Ocean reached number 10 in the Billboard Hot 100 chart. 

Selena’s Nashville performance made major headlines on Wednesday after it was revealed that her BFF Taylor Swift had been in the audience with new beau Tom Hiddleston.

Tom and Taylor were photographed leaving the gig hand-in-hand and inside the arena, were captured on cell phone video bopping along to the tunes.

‘Taylor invited Tom to go,’ a source told E! News. ‘Tom always wants to please Taylor and show her that her friends matter. Taylor likes that about Tom.’

The 26-year-old singer and 35-year-old actor were seen busting a move to Selena’s hit song Same Old Love in a Snapchat video.

The A-list couple were joined at the concert by Taylor’s close friend Abigail and her boyfriend Matt, according to E!. 

Selena will continue on the North American leg of her tour until July 11 in Quebec City, Canada.

Then she heads off for concerts around the world in support of her second studio album, ending in Mexico in December.

When she announced her tour earlier this year the singer said in a statement: ‘I am ready to get back on the road and see my fans in person!

‘This album marks a new and very important chapter in my life. I cannot wait to get on stage and perform this new material.’
