Nick Cannon Still Cares Enough To Promote Mariah Carey's Album

Carey is the 'hardest working woman' he knows.

Just because Nick Cannon and Mariah Carey are no longer a couple doesn't mean that the two can't support each other. On Wednesday, Cannon took to Instagram to promote his ex-wife's upcoming greatest hits project, calling her "The Queen."

"#1ToInfinity album in stores May 6th. #TheQueen #NoHate #HardestWorkingWomanIKnow," he wrote.

His next Instagram was a picture of him and an actress getting cozy on-set, but that's beside the point.

Mariah just released her new track "Infinity" this week, a heartbreaking orchestral ode to a failed relationship. Cannon filed for divorce from Carey in December. The couple continue to co-parent their children Moroccan and Monroe, and it's good to know that there's #nohate there.

Ms. Carey is in Vegas preparing for her residency shows beginning May 6. Her greatest hits album, #1 To Infinity, will be released on May 18.
