Kanye West has confirmed plans of a collaborative album with Drake. The pair teased a project in late August with a cryptic billboard in Los Angeles featuring the logos of their respective labels.

In an interview with Vogue about his Yeezy Season 4 collection debuting Wednesday, the rapper and designer spoke about the cryptic sign for the first time. “We’re just working on music, working on a bunch of music together, just having fun going into the studio,” he revealed without unveiling a title or release date. “We’re working on an album, so there’s some exciting things coming up soon.”

Both rappers contributed to each other’s most recent releases. Drake has a co-writing credit on West’s “30 Hours” off The Life of Pablo, while West appeared on the original version of Drake’s “Pop Style” from his April album Views alongside Jay-Z. West and Jay-Z were even billed as The Throne on “Pop Style,” referencing back to West’s first collaborative album Watch the Throne. Drake previously teamed up with Future for last year’s surprise mixtape What a Time to Be Alive.

West also used the interview to tease what’s next for him after his current Saint Pablo tour. Following the debut of Season 4, he plans to launch a children’s clothing line with wife Kim Kardashian West alongside establishing clothing stores around the world.

“I believe the first one will be in California, since that’s where I stay now,” he said. “I can go there most often, check in, get the vibe. But I want to do 200 stores in the next year. That’s just me saying what I want. I’m not saying what can definitely happen but you might as well just state out loud what you want. That’ll put you one step closer to getting it.”
