She's the new face of Atkins and Kelly Brook has been keeping her followers abreast of her weightloss journey as she vows to get the perfect summer body. 

Slipping into her workout gear, the 35-year-old was rocking a striped magenta sports bra and tie-dyed cropped leggings as she indulged in a pilates class. 

Posting a couple of shots of the session to her Instagram account, One Big Happy star, Kelly wrote, 'Pilates Wednesday Lets Gooooo.'

Dressed in a tight polka dot top, Kelly revealed a noticeably slimmer waistline.

She also showcased her legs, which looked remarkably more toned, in a thigh-skimming pleated skirt.

The model-turned-actress then completed her elegant look with a pair of black stiletto heels and a cute royal blue handbag.

Judging by her recent posts on Twitter, Kelly seems to be well aware of how much her appearance has been improving since she kick-started her healthier lifestyle at the start of January.
