And now she's also going to be seen as the face of a new fragrance, having been signed to BOSS Orange, which the actress describes as "musky, sweet and sexy," launching in the UK in July.
Commenting that the actress embodies the spirit of the brand, marketing director Thomas Burkhardt says: "She is a liberated soul – light-hearted, spontaneous and passionate – and she quite simply wears her heart on her sleeve, which captures the spirit of this new fragrance perfectly.”
Sienna will feature in both print and TV advertising to support the campaign, with the TV ads focusing on a series of close-up sequences which reveal different facets of her personality.
“The general mood of the advertising is relaxed and light-hearted," she commented. "There’s a casual yet energetic atmosphere with lots of running around and laughing – my idea of heaven.”
