This model’s flawless no make-up selfie just made us VERY jealous!

Kelly Brook's New Year's resolutions have been paying off, if this latest selfie is anything to go by!

The model took to Instagram to share a gorgeous no make-up snap last night, and she says her clear skin is all down to some lifestyle changes over the last few weeks.

The relaxed picture was captioned, "Day 12 of #NoSugar #NoCarbs My Skin is the best it's been in ages. No Fine lines or Blemishes!! Healthy Glow #MyAtkins is really paying off #Ad #Truth#NoFilter #NoMakeUp" 

Although the post seems to be part of Kelly's promotional work with the My Atkins diet plan, there's no denying that her skin has reaped the benefits of the model's new eating regime. 

Earlier in the day, the naturally curvy Kelly seemed to be lusting after a slimmer figure, as she posted a series of throwback snaps to her bikini modelling days:

The model has previously spoken about how she was unhappy with her weight gain over the last year, which she says has not been helped by the many "naughty treats" she's been indulging in during the filming of her US show One Big Happy.

Well, we think she still looks fab!

The star is currently living between London and Los Angeles as she completes work on the NBC show, but has been keeping fit with a mix of weight training and Pilates.
