'Last day of being 29!': Demi Moore's daughter Scout Willis wears nothing but bikini bottoms to mark the last day of her twenties

She has had her last day in her twenties.

And Scout Willis, who turned 30 on Tuesday, shared a teasing snap with fans on Monday, taking to her Instagram story to pose in chartreuse-coloured bikini bottoms.

Taking the shot from behind, Scout, who is the daughter of Demi Moore and Bruce Willis, left her top half bare, her back and legs smothered in sun cream.

The brunette beauty captioned her story: 'last day being 29', keeping her hair off her back.

She managed to capture her idyllic surroundings, posing on the stony water's edge. 

The water was perfectly clear and from the image, only one other person could be spotted enjoying a bathe whilst the sun shone.

'Truly, to me nothing is sexier than a woman who feels powerfully embodied and totally comfortable in her skin. I love @andieswim and the incredible women who make it because behind every suit is the intention to give each woman the opportunity to experience that radiant confidence. 

'This photo and this dynamic suit make me feel so good!' Demi's daughter wrote, alongside a full-length picture of her sporting a black swimming costume.

Family shoot: Perhaps the most standout shot for the campaign was Scout posing in the swimwear alongside mother Demi, 58 (in black) older sister Rumer Willis, 32 (in white) and younger sister Tallulah Willis, 27 (in red)
