This isn't the first time Liz has got fans gushing over her beauty on Instagram.

Back in February, the Bedazzled actress shared a saucy snap with her followers - stripping off and posing naked with nothing but a white fur throw to cover her modesty.

The bikini designer was branded a 'goddess' as fans and famous friends gushed over the sexy picture, with some delighted Instagram viewers declaring the actress the Queen of Valentine's Day.

Sitting on her bed with a full face of makeup and her brunette tresses teased into loose waves, Liz smouldered for the camera while teasing fans with the snap.
