Madonna, 66, flashes her black lace thong underwear in fishnets and a bustier top as she shares cheeky snaps with her horse

Madonna shared a number of sizzling snaps in a cheeky new Instagram post on Tuesday.

The Material Girl icon, 66, posted a carousel of photos, including two where she flashed her black lace thong underwear in a pair of fishnet stockings and a black bustier.

The hitmaker — who recently stepped out with her new boyfriend Akeem Morris, 28, who’s nearly 40 years her junior — also rocked a grey cowboy hat and a black jacket as she posed inside of a horse barn.

Other snaps showed her in a vibrant pink sheer dress, strolling with her horse Roller on a ranch.

In the caption she wrote: ‘Farewell, to long days and Hot summer nights………. Good-bye Summer. I’ll never forget you! ☀️. P.S. my horse is an Irish Sport Horse named Roller!! He has been so good to me and still riding strong but I’m looking to get a new one. Any Suggestions?’

The post started out with a snap of the singer in the pink dress and adorned with jewels, standing next to her horse in the nighttime.

The outfit was completed with a pair of knee-high black leather boots.

Her flowing blonde locks framed her face, and her striking makeup highlighted her impossibly smooth complexion.

Another photograph showed her laying down on the grass while Roller grazed nearby.

There was also a cheeky shot of her looking out onto the ranch, with her black thong peeking out from underneath her sheer pink dress dress.

The carousel continued with a photo of her smelling a bouquet of pink flowers.

She went on to strike poses inside, playfully lifting a leg onto a chair in a stylish black and white photo.

The post ended with a close-up shot of her stockings and a purple flower between her feet.

It comes a week after the star threw a lavish 12th birthday celebration for her twin daughters Estere and Stella.

The music legend took to Instagram last Monday to share outtakes from the party.

She wrote in the caption of a reel, ‘Happy Birthday to my Twin Virgos!’ adding at the end, ‘LOVE YOU BOTH SO MUCH!!!’

The soiree consisted of a water slide, arts and crafts, T-shirt and hat airbrushing, an ice cream truck, and horseback riding.

Stella and Estere were adopted by Madonna in February 2017 at the age of five. They were born in Malawi in August 2012.

The songstress is also mom to Lourdes, 27, Rocco, 24, David, 18, and Mercy, also 18.

Akeem, the singer’s much younger new flame, was part of the festivities.

The soccer star rocked a camouflage trucker hat that read ‘unstoppable’ across the front, adding a casual white button-up shirt.

He rode in a golf cart with Madonna and the pair indulged in vanilla ice cream cones.

The couple just returned from Italy, where they stayed the mansion of Madonna’s friend and acclaimed fashion designers Domenico Dolce and Stefano Gabbana.

Madonna and Akeem, who have a 38-year age gap, were pictured engaging in a string of steamy clinches last weekend during the lavish trip.

The Like A Virgin star first flaunted her new lover on July 4, just months after splitting from her ex boyfriend Josh Popper, who was 36 years her junior.

She first shared pictures of herself cuddling up to Akeem as they celebrated Independence Day together in New York City.
