Nickelodeon star Nick wrote a message to fans via Instagram on Wednesday (29 April), as he shared the cover photo of Mariah's new greatest hits album.
Captioning the snap, he said: "#1ToInfinity album in stores May 6th. #TheQueen #NoHate #HardestWorkingWomanIKnow."
Nick, 34, filed for divorce in December after six years of marriage to Mariah. Despite their split, Nick and Mariah both appear to be on good terms, with the pair having spent Easter together with their twins Monroe and Moroccan.
Meanwhile, Mariah unveiled her new single 'Infinity' this week, which many had described as heartbreak anthem.
Speaking to Extra, Mariah dismissed reports that it was about her marriage to Nick.
She explained: "Honestly, it's about loving yourself first. 'Infinity' is like love equals you first. There's a section of the song where it's like a chant - 'You're leaving, you're leaving, you're out the door infinity loving me more and more' - meaning you have to love yourself first.
"It can't be all about somebody else's thing or their issues; it has to be you and then you can deal with the rest of the things in your life."
