McCullum joined World Championship Wrestling in December 1999. After training in the company's Power Plant wrestling school, McCullum made her professional wrestling debut in 2000 under the ring name Midajah (her middle name) as part of a group of fitness models (Tylene Buck, April Hunter, Shakira and Pamela Paulshock) known as the nWo Girls. Midajah and Shakira soon transitioned into being the valets of Scott Steiner, who subsequently nicknamed them his "Freaks". After Shakira left WCW, McCullum then became the main valet for Steiner and became part of the Magnificent Seven. She had a brief feud with Leia Meow. She appeared on the final episode of "Nitro" in Steiner's corner as he was defeated by Booker T.
