"I had people when I was 13 telling me how ugly I was, and how could two beautiful actors create such hideous troll children?" she told Katie Couric in 2014 after her stint in rehab.
In her image, Tallulah looked fit with toned legs and a small waistline.
She also posed with her sisters for a group shot. All three looked incredibly toned as they were fresh out of the river that had a snowy embankment.
Rumer wore a red top that tied in front with little black briefs.
Tallulah looked slender in a red two-piece that had a bra top and high-waisted briefs.
And Scout had on a small strapless orange bikini top and striped boy shorts.
The ladies seemed to be wading in spring water as they were in an area that was blocked off by large stones.
Last week the three ladies posed together in a bathtub.
And earlier this year Tallulah showed off her bathing suit body again as she wore a white one piece with sister Scout.
The ladies have stayed close as they have each pursued careers in the arts like their parents.
Rumer is an actress and singer best known for her win on Dancing With The Stars.
She also played the character of Roxie Hart in Chicago on Broadway.
Meanwhile, Demi has been appearing on Empire. And she is in post production on the movie Love Sonia.
