In a Keek video posted by Bieber's mom Pattie Mallette, Justin and Cody are seen jamming out with a full out band. We're thinkin' the song could be called "I Won't Let You Down".
"I will follow back on keek everyone who comments on this video! Excited! Remembering @codysimpson @justinbieber," she tweeted on Friday, along with the link to the clip.
Cody recently talked to Idolator and revealed how the duo's pair-up came together (and might still be ongoing), while they both continue to prep their solo albums.
"We spent about two weeks in the studio together just messing around and wrote about 13 songs," he said. "We did it really casually and didn't make a big deal about it. It was something cool to pass the time while we're both working on our own stuff."
Cody explained, "The stuff I have with Justin is all very much based around romance and women." Wait, so does this mean this song is about Selena Gomez or Gigi Hadid?
