Mariah Carey and Nick Cannon split update alleged that divorce proceedings are ongoing as the couple gets busy with work. The "Hero" singer buries herself into preparing for her concert.

A source revealed to E! News that following the Mariah Carey and Nick Cannon split report, the singing diva already "started the divorce process."

Perhaps to take their minds off from the breakup, the estranged couple has been keeping themselves busy as Mariah Carey is preparing for her "The Elusive Chanteuse Show" while Nick Cannon has accepted several DJ gigs, as well as his regular hosting duties for "America's Got Talent."

After a DJ gig at the 2014 Toronto International Film Festival, and the Muzik Pool and Bar on Saturday night, Nick Cannon was in New York on Sunday night at The Ainsworth NFL Kick Off party.

But a source told E! News that his very busy schedule has been the source of the Nick Cannon and Mariah carey split, which could end up in divorce. The comedian and host have been staying in hotels although he still visits their daughters from time to time.

"This has been going on for months. He does not have to work, but he's been throwing himself into gigs and projects," the source said.

Despite some trouble in their marriage Nick Cannon continued to accept gigs, "again, he doesn't need the money. He just prefers to be really busy," the source added.

Meanwhile, Mariah Carey is focusing on her daughters as well as her career, which has been on hiatus ever since she gave birth. She posted photos on her social media account showing the singer rehearsing in a studio.

The People magazine said that "The Elusive Chanteuse Show" will be her first major concert since "The Adventures of Mimi" in 2006. The world tour will kick off in Japan next month.
