Are Hilary Duff and Tove Lo collaborating on some new music? Well, the singers certainly made fans freak the freak out when they both Instagrammed pics together in the studio. As anyone who follows Hilary on Instagram would know, the singer-actress is currently in Sweden -- and it looks like she's recording some new music, sharing a shot of herself today (Feb. 3) with the caption, "Jet lag recording… #sweden." Eek! Considering Hilary recently revealed why she took "a step back" from her music, we're so happy to learn that she's back in the studio, workin' on some new jams -- especially if they're with Tove Lo. "Got to hang with this talented beauty today @HilaryDuff," the 'Habits' singer captioned the above photo. "#studiotime #wolfcousins." Of course, Hilary also shared a snap from the studio session, posting a silly selfie of the two together. Check it out below!

While we can't wait for the premiere of Hilary's TV Land show 'Younger,' we are also insanely psyched for even more new music from the 'All About You' singer. We're ready!
