Britney Spears 'Work B*tch' Instagram Preview Includes Sexy Bikini Dancing in Las Vegas Desert, Wall Dancing by Pool [VIDEO/PHOTO]

The music video for Britney Spears' new single "Work B*tch" is well on its way, and it wouldn't be the modern era if the soon-to-be Las Vegas resident didn't tease the clip on Instagram.

Late last night, Spears posted a 15-second clip of the "Work B*tch" music video to her social media accounts. The sexy snippet shows the fit mama slithering down a white wall while in a bikini, staring into a mirror in the desert and standing on a platform with a variety of backup dancers in the Vegas sun.

Spears' body looks in top form for the "Work B*tch" music video, as she rocks a variety of bikinis and crop tops.

Check out the sexy Instagram preview for "Work B*tch" below.

This isn't the first time Spears has teased her new music video. One day ago, she posted a simple photo to her Instagram account, showing "B*tch" written in neon pink lights as a leg with black stockings and a lacy dress peeks into the frame.

Spears also posted photos from the set while filming "Work B*tch," which showed off her insane heels and abs, as she wore a stringy blue bikini.

The music video has yet to receive a premiere date, but with all the teasing on social media, it's bound to hit the Internet soon. The theme of "Work B*tch" seems to blend together the Las Vegas desert (playing into Spears' upcoming residency at Planet Hollywood), bikinis and Spears' fit body.

"Work B*tch" is the first single from Spears' upcoming eighth studio album, due out Dec. 3.
