We may know her best as the preened and polished Blair Waldorf, but in real life Herbal Essences spokesmodel Leighton is a real low maintanence girl and an advocate of natural beauty.
She does however have several fail-safe beauty secrets, which she recently revealed to Instyle US. She told the mag that she keeps things simple: 'I use a little cheek stain, curl my lashes, and put on some lip balm and sunscreen'.
She favours products which accentuate her natural beauty, including Smith's Rosebud Salve, which she says is her 'desert island beauty pick', and Benefit Benetint for 'the most natural flush'.
And while she revealed that her favoured way to style her hair when off duty is to let it air-dry, she still likes to give a little extra texture and hold courtesy of Herbal Essences Tousle Me Softly Spray Gel.
Right, we're off shopping to bag the secrets to the American beauty's radiant look.
