Rumer, 34, stood in a skimpy white bikini top and matching bottoms which revealed the sliver of a small tattoo on her inner thigh.

Her curly red locks fell down to the middle of her back. Bruce Willis and Demi Moore’s oldest child enjoyed a drink from Cali Coffee while leisurely floating on an inflatable strawberry.

Later on, Rumer took a running leap into the pool, her hands high above her head, before landing in the crystal blue water.

Rumer’s little sister, 28, wore a bandeau-style bikini with the New York Knicks symbol emblazoned on her chest. She added dark green, metallic bikini bottoms to the look.

Tallulah tied her hair up in a tall brown bun that sat near the back of her head and kicked water around while Rumer laughed alongside her. A couple days after the pair posed at the photoshoot together, their father Bruce Willis was spotted taking a photo with a fan in a rare public outing.

The 67-year-old Die Hard star was pictured laughing and smiling as he greeted a female fan and her child outside the Shutters on the Beach hotel where he is said to have enjoyed lunch with a friend.
