Ava is an awesome child who had rocked out at more concerts than grown ups. She enjoyed great fangirl moments with the world's music icons like Taylor Swift and Gwen Stefani.

An avid fan of Swift, Ava sings "Blank Space" every day. She attended the pop star's show in Los Angeles and had a great time as Swift stopped backstage to say hi to her. She also did not miss Stefani's "This Is What the Truth Feels Like" tour in Los Angeles.

AJ shared a photo of his daughter with Stefani on social media. He thanked the "Hollaback Girl" singer for being sweet to his baby girl.


 

AJ's tot appreciates all music genres. She loves the Beatles and Stevie Wonder whose songs were at the top of her first birthday party playlist. She dances with Justin Beiber tunes despite being a child of a Backstreet Boys singer, Yahoo has learned.

The cute music fan does not make the mistake of missing out her dad in her idol's list. She is actually having her dad as her biggest musical love. She likes to listen to his music every night during her bath time while dancing and singing to the tunes.

AJ's wife Rochelle McLean would send him videos of Ava singing a capella songs from his upcoming album. The little girl is also excited to have a younger sibling even before the announcement of their second baby's gender.

"She has her own little baby that she's been tucking under her shirt like she's pregnant!" the Backstreet Boys singer told Entertainment Tonight. "She's like, swaddling her babies now."

Here is a clip of Ava dancing:
