And Lizzo was her own best advertisement as she showcased two of the looks on her Instagram page on Tuesday, flaunting her curves in the form-fitting garments.

The singer, 38, slipped into a bright purple co-ord, which consisted of a cleavage-boosting sports bra and a pair of cycling shorts.

Lizzo showcased all angles of the ensemble, as she turned away from the camera to reveal her peachy bottom.

The American star declared ‘look at this smooth body’ as she waxed lyrical about the quality of the clothing in a video shared to her social media.

Lizzo admitted she ‘wasn’t a shorts girl’ but was loving the results of the shapewear,  as she told fans to ‘run not walk’ to go and buy the line.

Another look saw Lizzo in a similar pink two-piece, as she continued to rave about the line while flaunting her body in front of the camera.

She captioned the clip: ‘RUN, DONT WALK YALL— this new nearly naked & smoothed reality is GIVINGGGGGGUHHHH only at @yitty.’

In the videos, Lizzo wore her curly locks loose and opted for a flawless coat of make-up in pink tones, completing the look with a metallic manicure.

It comes after Katy Perry, who is reportedly upset at the backlash she has received this season on American Idol, said she thinks Lizzo would make the perfect addition.

The California Gurls singer issued the invitation to the Grrrls artist while participating in one of Buzzfeed Celebs Puppy Interview segments.

When answering a question about the most challenging part about being a judge, the singer answered, ‘Probably being a woman and having a strong opinion.’

To remedy the situation, she said, ‘I’d like Lizzo to come and join American Idol.’ Clarifying the offer, she continued, ‘This is an invitation from me, Katy Perry.
