Despite Rumer's body confidence, the star recently revealed that she couldn't follow her younger sister Scout in posing topless.
'She's very bold... I give her mad props for that,' she told Access Hollywood. 'I don't know if I'd be brave enough to do it.'
Scout's campaign began in a protest of Instagram's policy of deleting photos which show a woman's exposed nipple.
Rumer's modelling work comes as the star spends time concentrating on her singing, having begun her career as an actress, starring in movie such as The Whole Nine Yards and House Bunny.
She also celebrated her birthday recently with a cake in the shape of a gun. 'Best birthday cake ever. Thank you mama,' she wrote alongside a snapshot of the treat.
