Who knew she had it in her?!

Rumer Willis likes to push the envelope but took it an extra step further when she showed some serious skin with sunscreen while starring in a music video spoof to Ariana Grande's hit song Problem.

The 25-year-old actress, alongside Constantine Rousouli and Jake Wilson, wasn't doing this only for fun as they altered the lyrics to promote using sunscreen in the awesome PSA Wilson wrote and directed. She's got Iggy Azalea's rhymes down!
