Demi Moore flaunts her flawless body in poolside snap with daughters

Hey, Tallulah, is that your older sister?

We're not kidding -- Demi Moore looked flawless and nearly half her age in a recent Instagram posted by her daughter, Tallulah, on Sunday.

The 52-year-old actress rocked a tiny red bikini as she posed between daughters Tallulah, 21, and Scout, 23, for a poolside snap. And her toned physique had jaws dropping! Moore, who is known for her fab abs, looked better than ever next to her kiddos and showed off her strong arms and svelte legs.

Since she's on tour with "Dancing With The Stars," Rumer, 26, was nowhere to be seen -- but the dancer recently showed off her hot mom in a lookalike snap.
