No. 1 Belieber Billie Eilish Just Took Her Fandom to the Most Extreme in 'Seasons' Finale

It is no secret that Billie Eilish is the world's biggest Justin Bieber fan, so of course she made an appearance in the Seasons finale. But what she said in her cameo may be a little more shocking.

"Anything that he makes at all, I'm excited about," Eilish said in an on-camera interview. "I don't care if he pooped and put it on a plate and put that in a store. I'm excited! Anything that Justin makes, I'm ready to go."

Eilish is one of several Bieber collaborators who expressed their love for Justin in the Seasons finale -- which premiered for YouTube premium members on Tuesday (Feb. 25) -- including his "Intentions" partner Quavo and his longtime mentor, Usher. Eilish offered a perfect balance of fangirl and fellow pop star, assessing how Bieber has grown over the years.

"I would say that he's doing better and that makes me so happy because, you know, I like, care about him more than, like, anyone in my life," she said with a laugh. "The fact that he's just moving forward and going, and going, and going, is huge. I think it's bigger than all of us even realize, because it's easy to stop."

Bieber himself recognized how his perspective has changed since he was a teen, admitting that he was more focused on himself than other people. "Now going out there and setting the tone is really what I want to do," Bieber said, talking about his next tour. "My whole perspective change is going to make everything run a lot smoother, make me happier, make the people around me respect me more."

Usher and Scooter Braun, who discovered Bieber, also talked about the "Yummy" singer's evolution, which Usher said "is still underway." DJ Khaled, Big Sean and Quavo all gushed about what a great friend Justin is, with Quavo asserting that he's one of the best artists in the world because "he's himself, and he shows it in the music and he shows it off the microphone."

The rest of the 16-minute Seasons finale features behind-the-scenes footage from the Seasons premiere in Los Angeles (where Braun surprised groups of fans with tickets to the showing), Bieber celebrating the Changes release with his team, and even meeting one of his One Less Lonely Girls all grown up.
