As per Roberts, the secret to beauty is to ‘smell good’

The 50-year-old actress – who recently shot her second fragrance campaign for Lancôme's La vie est Belle perfume – insists a beauty regime doesn't need to involve much more than a happy expression and a favourite scent.

She told People magazine, "I think as long as everybody smells good and has a smile on their face, that's a beauty regime."

The perfume is the second best selling in the US, and the publication were treated to a sneak preview of the newest campaign, featuring the 'Notting Hill' star's iconic smile.

The series of photos shot by photographer Alexi Lubomirski, show Julia – who has been a face of the brand since 2010 – dressed in a thigh length, long sleeved, white dress, walking through a crowded street while it rains.
