Lil' Kim joined forced with DMX during a show in Scottsdale, Ariz. over the weekend. The duo awed fans with a performance of the 1998 hit song 'Money, Power, Respect.' "New York is in the motherf---in' building!" DMX shouted to fans.

Both Kim and DMX are said to be working on new music. Following his release from an Arizona prison on July 7 for probation violations, footage of X recording new music surfaced online. And last week Lil' Kim revealed she is making progress on a follow-up to 2005's 'The Naked Truth.' "I am working on my album," she said in an interview. "I'm gonna be dropping some singles soon. I'm not concentrated on dropping an album so soon, but I will be dropping singles ... I'm gonna be working with a lot of great people on my album."
