Rumer Willis Parodies Ariana Grande's "Problem" With "SPF": See the Sexy Video

Spreading the word—and the sunscreen! Rumer Willis is featured in a funny, raunchy music video by Broadway performer Constantine Rousouli, a parody PSA for sunscreen titled "SPF." Spoofing Ariana Grande's hit song "Problem" featuring Iggy Azalea, Bruce Willis and Demi Moore's oldest daughter takes on the song's whispering parts: 

"Rub that SPF on, you gotta rub that SPF on, you gotta rub that SPF on, you better rub that, rub that s--t on..."  

Throughout the clip, the 25-year-old actress squirts lotion on the chests and torsos of various shirtless men. During a rap break performed by director Jake Wilson instead of Azalea, Willis swivels her hips and flips her hair while wearing a black bikini. 

Later on, Willis wears a sheer one-piece swimsuit with strategically placed star-shaped pasties. Encircled by multiple men in a pool, she sprays SPF at the camera while dancing.
