Carly Rae Jepsen and Jack Antonoff Are Back in the Studio Together

Longtime collaborators and pals Carly Rae Jepsen and Jack Antonf have reunited.

Jepsen posted a photo late on July 1 on Instagram the duo laughing in the studio, captioning it, "@jackantonf and I having absolutely no fun in the studio tonight."

Antonf has helped write and produce songs for Jepsen in past; most notably, he worked on the "Call Me Maybe" singer's 2015 album EMOTION, although his songs didn't make the tracklist.

Returning the favor, Jepsen recorded vocals for the re-imagined version the Bleachers' song "Shadow," f their 2015 album Terrible Thrills Vol. 2.
