Mariah Carey is back to work. Less than six months after giving birth to her twins, the new mom returned to the studio to begin her next album. She and longtime collaborator Jermaine Dupri posted photos of themselves in the lab.

“So happy to be back in the studio with the one & only @Mr_Dupri aka Jermash!” wrote MC, while JD added, “We are back together.”

The dynamic duo last collaborated on “Oh Santa” off last year’s holiday album Merry Christmas II You. Mariah will also make an appearance on the U.S. edition of “The X Factor” as Simon Cowell’s guest.
