After revealing that she dyed her hair brown, Demi Lovato is back in the studio!

According to the “Neon Lights” singer, she is teaming up with the Creative Director for her tour and friend, Nick Jonas, to write new music together.

After posting a selfie of her fresh brunette locks on Thursday, the singer tweeted, “Music studio magic with @nickjonas.. The best song we’ve written together yet. #smash”

According to MTV, Demi and Nick are used to writing songs with one another. In an interview, Nick said he was ”a big part of [Demi's] first record, Don’t Forget,“ and after that he helped to craft her second, Here We Go Again.

While there is no release date for when the single will make its debut, we will be waiting to see what “music studio magic” the duo have created.
