Nick Cannon proved there is nothing but love between him and his ex [1] Mariah Carey when he gave her a sweet Mother's Day shout-out on Instagram on Sunday. Nick posted a photo of Mariah and their twins, Moroccan and Monroe, with the following caption:

"Gotta represent for the Mother of my children. She is such a wonderful, thoughtful, festive, loving and nurturing Soul. I will forever be in debt to you for blessing me and the rest of the world with Roc & Roe. A true #Queen Will love you always @MariahCarey #HappyMothersDay."

Nick and Mariah, who split last Summer after six years of marriage, have recently been putting their differences aside to spend time together as a family. The pair celebrated Easter together [2] and also reunited for their twins' fourth birthday on April 30. And after Mariah's new song "Infinity" seemed to throw major shade at her ex [3], Nick cleared up any rumors of bad blood last month when he posted a photo of her new album cover on Instagram with the caption, "#1ToInfinity album in stores May 6th. #TheQueen #NoHate #HardestWorkingWomanIKnow."
