Lady Gaga doesn’t do too many collabos, so when she does, it certainly grabs our attention. Like that false story about her working with Eminem.

The Mother Monster confirmed via her massively followed Twitter account and her fledgling Little Monsters site that she is indeed appearing on a track on Lamar’s upcoming Interscope debut, ‘good kid, m.A.A.d city.’ It’s titled ‘PARTYNAUSEOUS.’

Since Gaga and Lamar call the same label home, it’s easy to see how and why this partnership blossomed. Gaga had been tweeting to and about Lamar for quite some time, sparking rumors of a collabo. She also caught his set at the Pitchfork Festival earlier this summer in Chicago, which further sparked suspicion. Now she has confirmed the news.

On her Little Monsters.com site, she shared a photo and wrote: “I am so excited to announce that a record I’ve been working on has now become a collaboration with @KendrickLamar for HIS ALBUM. It is dropping Sept. 6. It’s called “PARTYNAUSEOUS.”

PARTYNAUSEOUS? We like sound of that. We kept it all caps like Ma Monster did, since she reminded the media that her ‘ARTPOP’ project is all caps, too. See, we pay attention to deets.

Her tweets however, left out the title and the drop date. Those are below. She also shared how the magic happened with Lamar, too!

Lucky for Lamar to have a major, A-list feature such this on his debut. That’s what we call making an entrance.
