Posting a photo of himself with Hailey in the studio, Bieber not only let his fans know that he's recording new music, but that he calls Hailey is "studio chicka".
"Studio vibes.. with my studio chicka .." he wrote.
But that's not all.
In another post, Justin showed off another nickname, "goo goo."
"New nickname for her every day today she’s my goo goo," he wrote.
Ah, love is real.
