She may be leaving the modelling world behind, but Cara Delevingne is doing so with a bang.

In her latest campaign for Yves Saint Laurent, the 23-year-old has stripped down to nothing but a blazer in the sultry ad.

Promoting the brand’s Rouge Pur Couture lipstick, it’s debatable how many people will actually take notice of the crimson shade as Cara lounges back in a leather chair!

The British star recently announced plans to leave the modelling world behind to focus on a career in acting.

After making fame on the catwalk and fronting numerous campaigns with her bold brows, Cara has taken to the big screen with roles in Paper Towns, Suicide Squad and Anna Karenina gaining her notoriety.

We can’t wait to see where her next role takes her!
