He might have the new No. 1 album in the country, but A$AP Rocky has additional material on the way in the form of a joint mixtape with Rod Stewart.

Rocky told Vulture in a new interview published Wednesday that he and Stewart "have a mixtape coming out. It’s called Born to Be Pretty and it’s definitely a panty-dropper. Droppin’ this summer. You already know."

The revelation follows the duo's recent collaboration "Everyday," featuring Miguel and Mark Ronson, which is featured on Rocky's new album At.Long.Last.A$AP, which debuted at No. 1 in the U.S. this week.

Update: A$AP Rocky said on Thursday (June 4) that he was simply joking about releasing a mixtape with Rod Stewart.
