The duo know each other from their Columbia Records days, when Jackson was vp A&R during the 1990s and Carey was signed to the label from 1988 to 2001. Through the years, Jackson, 55, has produced, co-written and appeared on many Carey recordings and played bass for her in the studio and on the road. Among his credits: Jackson wrote and produced two songs for her 2001 film Glitter, and on her 2005 smash The Emancipation of Mimi, he played bass and was in the video for her cover of Def Leppard's "Bringin' on the Heartbreak." He also produced her 2010 holiday album Merry Christmas II You.

Carey, 41, previously was signed to Chris Lighty's Violator Entertainment, which represents such artists as 50 Cent, LL Cool J and Soulja Boy. In September, the company merged with Primary Wave, management home to Cee-Lo Green and Eric Benet.

Jackson is no stranger to management, having worked with funk-rocker Nikka Costa, soul singer Van Hunt and North Carolina-based band Paper Tongues. He's one of several notable musicians who also guide the careers of others. Sean "Diddy" Combs has managed rapper Notorious B.I.G., Making the Band winner Danity Kane and most recently reportedly was working with Nicki Minaj and Rick Ross. Jay-Z, by virtue of running management company RocNation, has a hand in the careers of Rihanna and Willow Smith. Usher, in partnership with Justin Bieber manager Scooter Braun, can lay claim to some of the pop phenom's success.

On Nov. 2, Jackson was in full management mode as he accompanied Carey to film the music video for "All I Want for Christmas Is You," her duet with Bieber. The nine-hour night shoot took place at Macy's Herald Square in New York, and according to observers, Jackson stayed for the duration. A few days later, he was seen at Carey's label offices taking meetings. Says a source, "He's very much in the mix."
