Nicole Scherzinger turns up the heat in steamy working out video in bikini

Former Pussycat Dolls leader, Nicole Scherzinger, 43 turned up the heat on Saturday when the gorgeous singer posted a steamy workout video dressed in a bikini.

"I don't dance... I WERK," the 43-year-old Hawaiian beauty wrote beside the steamy video. The television personality wore a brown wrap-around bikini which allowed her 5 million Instagram followers the perfect view of her enviously toned body.

Nicole Scherzinger started the workout video by doing a series of lunges while holding weights in each hand, before moving on to a quick spin on an exercise bike followed by leg extensions and then a couple of fun twerks on the workout bench.

Clearly the workout out was quite difficult, because the Don't Cha singer workout up quite the sweat!

Many of Nicole's Instagram followers were delighted by the post, and many made sure the former Pussycat Doll knew it.

"Thee ONLY BAWDY!!! Sheeesh Nicole !!!," a supportive follower wrote in response to the video.

While another added, "The hottest woman in the world. Period.???"
