Tallulah, of course, wasn't blind to her mom's in-shape body, using the hashtag "mymomsbodtho" in her caption of the family snap.

Tallulah is more covered up in the shot in a one-piece, but she looks fit. But, Demi steals the show in her red and white patterned two-piece that revealed her tight tummy and toned legs.

Many of Tallulah's followers showered praise on Demi, asking which one of the three was the mother.
