Billy Joel's Daughter Celebrates with Her Dad's Song!

For Billy Joel's daughter Della's birthday, she grabbed the microphone and performed one of her father's songs to mark the special occasion.

Joel shared the video Sunday to social media, as the three-year-old sang "Don't Ask Me Why," which he wrote is her favorite.
