“Christina is, like, one of my favorite collabs,” he said, noting that what led to them working together was “Let’s Get Dirty,” a song Redman did with DJ Kool that Aguilera liked.

“[DJ Kool] made a R&B/pop version of that record,” the rapper continued. “So I got on the record and after that, that s**it took off. We was everywhere, bro. She brought me on tour, we was overseas. That album, [Stripped], was one of her biggest albums.”

“And we was everywhere and I got to actually see how a pop artist shakes and moves through this industry, and it’s another level than hip-hop,” he added. “And plus, my publishing check? Oh my God! My publishing check, ni**a? I couldn’t believe I got that much money for one verse. It was over, like, $250k, my first check.”

Back in 2002, the same year “Dirrty” was released, Aguilera spoke with CD:UK about how the collaboration came about.

“I’m a big fan of Redman… and he did a song called ‘Let’s Get Dirty,’ which was a huge hit and I love that song,” she said at the time, adding, “And experiencing the club life myself, being 21, turning 21 over the past year, I wanted my first single to kind of have that hip-hop, club feel.”
