Melinda Midajah McCullum is an American personal trainer, fitness model and former professional wrestling manager, better known by her ring name, Midajah. She is best known for her appearances with World Championship Wrestling from 1999 to 2001.

McCullum received a certification in personal training and nutrition in 1994. She then worked as a personal fitness trainer with several companies. Subsequently, she worked with a bodybuilding supplement company, in trade shows, and made personal appearances.

Between 1997 and 2000, McCullum was the cover model for fitness magazines such as Iron Man, MuscleMag and Muscular Development.

In 1999, McCullum's agent, Rich Minzer, introduced her to Terry Taylor, an agent with the professional wrestling promotion World Championship Wrestling, who was recruiting fitness models. Taylor subsequently hired McCullum to serve as a valet for the New World Order stable.

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 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.

After WCW was acquired by WWE in March 2001, Midajah went on to participate in fitness competitions and model for fitness magazines such as Muscle & Fitness.

In 2002, McCullum joined World Wrestling All-Stars and resumed managing Scott Steiner and also began managing Perry Saturn.
