Looks like Slim Shady is a fan of good kid, m.A.A.d city. Following a performance at Firefly Festival in Delaware this weekend, MTV caught up with Kendrick, who dished on his visit to Detroit earlier this month, where Eminem summoned him to the studio. "I bumped heads with Eminem [in the past], but it was very brief, that was my first time really chopping it up with him, getting to ask all the questions I wanted to ask him," Kendrick recalled. Unfortunately for us, Kendrick didn't divulge whether or not the two got to actually record together.
