This would be a dream come true!

We caught Justin Bieber heading into Jim Henson studios yesterday afternoon, and we couldn't believe our eyes when minutes later, John Mayer arrived! Could they be working on new music together? Joining forces would pretty much guarantee some hits!

The two have been having a low-key bromance for some time, so it's not crazy to think they might collaborate on some new tunes. The Biebs has showed his love for the musician by rocking his concert t-shirts, while the "Gravity" crooner publicly came to JB's defense last year after he announced his decision to cancel the remaining dates of his Purpose tour.

"When someone pulls remaining dates of a tour, it means they would have done real damage to themselves if they kept going. We've lost so many great artists lately. I give Justin [thumbs up] for realizing it was time to call it. You should too," Mayer wrote on his social media.

In other news, we wonder what the "Sorry" crooner thought about ex Selena Gomez's Met Gala look? He skipped fashion's biggest event, and decided to keep it real on Instagram instead.

"Hey world, that glamorous lifestyle you see portrayed by famous people on Instagram don't be fooled thinking their life is better than yours I can promise you it's not!" he wrote.

Proving he's just a regular guy, Justin hit SoulCycle looking sleepy and disheveled this morning!
