Considering he has usually accompanied Billie onstage when he's performed until now, we were curious how he handled the audience, and if he took any cues from Billie herself ... seeing how she's got incredible stage presence and knows how to rock a crowd.
Turns out ... Finneas actually took diligent notes on how Billie handles herself during a performance, and it sounds like he applied some of those techniques for his own gig.
Now, for the juicy question ... does he, ya know, resent folks who might show up to his shows just because they're Billie fans? Check it out ... Finneas is a class act, telling us he'll take the support either way, but he DOES appreciate one type of fan in particular.
As for whether his own music career could lessen his time with Billie in the spotlight, he says he hopes not ... cause he loves jamming out with her. Awwww ... sibling love!!!
