Nick Cannon promotes ex Mariah Carey's new album

Los Angeles: Nick Cannon and Mariah Carey may have called it quits, but the TV host is still rooting for her and singing the praises of her new album.

Cannon, 34, posted the cover of Carey's new greatest hits compilation, #1 to Infinity, on Instagram.

"#TheQueen, #NoHate, and #HardestWorkingWomanIKnow," he wrote. Cannon also reminded fans that the new album hits stores on May 6.

The post would seem to combat rumours that he and Carey are on bad terms following their split.
