One famous family is after some social media attention this Christmas.

The daughters of Demi Moore and Bruce Willis – Rumer, Scout and Tallulah – have sparked a frenzy on Instagram by sharing a snap of themselves naked in the bath tub.

The siblings proved their sisterly bond to the world in the bizarre photo, which showed them protecting their modesty under the water with their knees up against their chests.

It was the youngest of the group, 23-year-old Tallulah, who took to the social media platform to share the snap, simply captioning it with three angel emojis.

The girls appear to be sitting in a hot tub style bath, which was in front of a spacious garden with lots of trees.

Some of the star's 167K followers went wild over the shot, with one person commenting: "SUCH BABES".

While another put: "Talk about quality fam time".

A third wrote: "Hottest chicks around❤️".

The snap has become one of the most liked posts on the star's Instagram page, but her most recent photo of mum Demi is fast catching up.

The ageless actress, 55, appears to be standing in a kitchen wearing a Christmas jumper with Barack Obama's face on it in a Christmas hat with the words: "Miss me yet?" beneath his face.

Tallulah captioned the funny shot: "D does politics", which sparked excitement among her followers.

The young star has been fairly vocal about growing up in the public eye, and caught the world's attention during the summer by sharing a picture of herself acknowledging her past eating disorder and addictions.

She described herself in the malnourished picture as "a malnourished string bean with aches that echoed throughout my soul".

The snap, which shows a 20-year-old Tallulah looking much thinner than she is today, also reads: "I did not value myself, my life or my body and as such I was constantly punishing for not being enough."

It concludes with: "I don't push any agenda, I can only speak for my path and staying sober has been far and beyond the most important thing I've done in my wee 23 years."
