Getting hearts pumping! Mariah Carey hits the gym in cleavage-baring lingerie and HEELS

It's not exactly the best choice for a workout.

But Mariah Carey didn't seem to be fazed as she strutted her stuff in the gym wearing nothing but fishnet stockings and black corset-style bodysuit on Thursday. 

The 46-year-old wore a 'sporty' jacket over the interesting choice of workout gear.

She's got it! Mariah Carey, 46, strutted her stuff in the gym wearing nothing but fishnet stockings and black corset-style bodysuit on Thursday

Take sports luxe to a new level in boots by Fenty x Puma

Just as we can thank Kim Kardashian for making bodysuits and latex dresses a thing, Rihanna is your gal when it comes to the sports luxe look.

Her Fenty x Puma collection is catching on in the celeb world being spotted on the likes of Hailey Baldwin, Gigi Hadid and now, Mariah Carey. The pop superstar wore a pair of the brand's high heels sneakers along with a bodysuit, fishnet stockings and a varsity jacket.

We love how these boots have the signature Puma wave on the side, as well as the number 13. The lace up front gives them a sporty feel, which sharply contrasts with the pointed toe, so you really do get the best of both worlds with these boots!

They're currently being sold at Farfetch so click through to their website (right) to snap up a pair of your very own. And for more options in every price range check out our selection below.

Instead of running shoes, the diva opted for a pair of lace-up heels from Rihanna's FENTYxPUMA collection. 

The Heartbreaker songstress posed for various photos around celebrity fitness trainer Gunnar Peterson's gym. 

Although she doesn't appear to be working up a sweat, Mariah looked good as she climbed up a stair climber, turning around to strike a pose. 

She later used the carpet in the gym as a catwalk where she strutted her stuff between the weight machines.

She appeared to be 'working hard' while lifting 20 pound weights showing off her strength and stamina.  

The singer wasn't shy about baring it all as her cleavage popped out above the tight bodysuit and she sported huge diamond necklaces around her neck. 

Mariah definitely got one fan's attention with her racy workout. Rihanna excitedly posted a photo of the singer posed up on a cardio machine in her shoes. 

Big fan! Rihanna was excited to see the singer wearing her shoes in the photos

'Yo I made it!!! @mariahcarey in #FENTYxPUMA,' she excited captioned the post. 

Earlier the day, Mariah was in the same outfit as she streamed a live video to her official Facebook page from what she said was a hotel room in Los Angeles on Thursday and it went viral almost immediately.

The 46-year-old's video was viewed over one million times in the first hour.

Going viral! Mariah Carey streamed a live video in lingerie to her official Facebook page from what she said was a hotel room in Los Angeles on Thursday; it went viral almost immediately

The singer wore a black body, cut high on the thigh as she stretched across white sheets in the romantically lit bedroom. 

Her long legs were almost extended and toes pointed, covered with sheer, black fishnet stockings, as she draped her hand along her thing.

Mariah laughed as she read comments from her viewers. She said, 'I can't say some of these things! It makes me sound like I think I'm sooo great.'

New music! The point of the live stream was to promote the released of her new single, 'I Don't,' featuring rapper YG, whose legal name is Keenon Daequan Ray Jackson

The point of the live stream was to promote the released of her new single, 'I Don't,' featuring rapper YG, whose legal name is Keenon Daequan Ray Jackson.

The breakup ballad was written about one month ago, as a response to recently calling things off with ex-fiancé and Australian billionaire James Packer. 

As fans on the stream started telling the Grammy winner how much they loved 'I Don't,' Mariah mentioned that what she's posted on her Instagram account was actually just a teaser. 

Not so subtle: Part of the teaser for the song featured a title screen with the words 'I Don't' in gold and silver glitter, with the letters spelling out 'I do' strategically emphasized

The end: Calling it quits with her ex-fiance just before the Grammy winner's E! docu-series, Mariah's World, premiered in December 2016 is what prompted the song

'It's so weird to me that people haven't heard the whole song,' she said.

Then a staff member let her know from off camera that her new single's roll-out would be at midnight around the world, so some people have actually already heard it.

Some 'lambs,' as Mariah affectionately calls her following, loved it so much that they started asking if and when the singer would be putting out a new album.

But the Mariah's World star let them know that's not quite in her plans at this time. 

Boy, bye! In the video she rolls around on top of a convertible in alternating white lace and black leather as she sang about how her lover probably thinks she's coming back, but is wrong

She said she's doing singles because it's more fun for her and doesn't want to stress right now about putting an entire album together up front, but that she hopes to release enough singles to be able to put them together in an album at the end of this recording streak. 

Always full of surprises, the Billboard award winner also let her fans know she's currently working on a new secret project with an unnamed but 'very talented' friend.

For now, 'I Don't' drops worldwide at midnight, local time, on Friday.
