Charlie Brown, Peppermint Patty, Snoopy and the rest of the Peanuts gang are welcoming Meghan Trainor to the club.
The "All About the Bass" singer is contributing to the upcoming animated The Peanuts Movie feature film with a song called "Better When I'm Dancin'".
As for the inspiration behind the song, the 21-year-old told People, "They wanted a song about confidence and knew I was good at writing those. I feel better when I'm onstage dancing and having fun, so I wrote about that!"
