Child prodigies Elias and Zion Phoenix got to replace Ellen DeGeneres for a night and interview Kristen Bell at an event for her company This Bar Saves Lives on Oct. 16.

The piano-playing Internet sensations made sure to cut right to the chase with Bell, asking the Frozen actress what her favorite part about playing Princess Anna was. "How spunky she is and how goofy I get to be," Bell, who is expecting her second child, told the two youngsters.

Elias and Zion performed at the event but made sure to also track down Bell's husband Dax Shepard. "Dax you are so famous," they adorably exclaimed upon meeting the actor. After asking Shepard to follow them on Twitter, the second-time dad-to-be joked, "I try not to follow minors on Twitter — it just looks weird."

At the event, Bell admitted to Us Weekly her daughter Lincoln doesn't know what Frozen is yet. "She hasn't seen [it]. She's too young. She doesn't even know it exists [but] I sing her lullabies and she's heard some of the songs."
