It was big news last weekend when Lady Gaga crashed the Pitchfork Music Festival in Chicago, to check out Kendrick Lamar's set. It looks like the pop star is rather taken with the hip-hop artist.

That Grape Juice says that a picture has arrived on the net of the two "in the studio," with Mother Monster wearing a pair of headphones. She had previously Tweeted her admiration of his tracks. "@kendricklamar #womenweedandweather listening to The Recipe. Can your new album come out now so i can go out to clubs and dance again."

Lamar has a new album on the way, but so does Gaga, and she'll be revealing the title to it in September. Do you think they'll show up on each other's album?

Lamar's album "good kid, m.A.A.d city" is due Oct. 2.
