Dakota Fanning turned 27 on Feb. 23 and her younger sister Elle Fanning, 22, celebrated the occasion with a new fun and eye-catching video! The birthday girl was standing up in an outside pool while wearing a red, yellow, and green plaid bikini that showed off her fit figure and was holding onto a pool skimmer in the clip. She was also rapping along to Cardi B‘s hit song “WAP” without missing a beat as she looked at the camera.
