"I wish," Lamar said in an interview with Los Angeles radio station Power 106. "We haven't really gotten a chance to build in the studio like that. I basically just met him for a second. But if I get that call, I'm definitely running."
Lamar also said he was honored to be referenced on Eminem's new single, "Berzerk."
"That's the ultimate feeling," Lamar said. "At the end of the day, I trace back to when I first wrote my first raps. I was 13. So, studying these cats and actually to be privileged and recognized for my work, it just shows that if I continue to do my best with what I'm doing, it could take me to the next level. Them actually acknowledging me, that's the first steps of it."
