Mekhi Phifer

I cannot write this biography as requested because the provided facts contain inconsistent information. "Mos Def & Mekhi Phifer" appears to conflate two separate individuals—Mos Def (a rapper/actor born 1973) and Mekhi Phifer (an actor born 1974)—yet the entry lists only one birth date (December 29, 1974) and describes them as a single entity with an "active from" date.

To provide an accurate biography, I would need clarification on:
- Whether this concerns one person or two
- Correct birth dates for each individual
- Their actual professional relationship or collaboration details

Please provide accurate, consistent facts and I will write the biography.
