Kevin Jonas's daughter Alena Rose is his biggest fan, and totally a daddy's girl. And it's downright adorable.

In a new video posted to Kevin's Instagram, the eldest Jo Bro is sitting on the stairs with his guitar, as he plays an old Jonas Brothers song "BB Good" on his acoustic guitar. Alena is standing in front of him watching, and then eventually starts clapping and adorably waving her hands in the air. 

If this isn't the cute face of The Jonas Brothers's biggest fan ... 😍.
