The 42-year-old star paid tribute to his spouse after she candidly opened up about their relationship.
He wrote on Instagram: ''Congrats to my bad ass wife @pink !!!!! She can do it all. Bad ass biker woman, amazing mother, best friend, and platinum selling artists! Congrats on the amazing album release today, and I can't wait to see you kick ass on Saturday Night Live tomorrow! Love you baby. (sic)''
It comes after Pink revealed her and Carey have gone a year without sex.
She explained: ''There are moments where I look at [Carey] and he is the most thoughtful, logical, constant ... he's like a rock. He's a good man. He's a good dad. He's just the kind of dad I thought he'd be and then some.
''And then I'll look at him and go: 'I've never liked you. There's nothing I like about you. We have nothing in common. I don't like any of the s**t you like. I don't ever wanna see you again.'
''Then two weeks later I'm like, things are going so good, you guys. Then you'll go through times when you haven't had sex in a year. Is this bed death? Is this the end of it? Do I want him? Does he want me? Monogamy is work! But you do the work and it's good again.''
And the 'So What' singer had previously joked that she sometimes wants to ''stab'' her spouse with a fork when things are rough between them, but said the key to making it work is to ''laugh as much as possible''.
She shared: ''I just try to laugh as much as possible. And we go through moments where honestly I look at him and I think, 'I've never liked you at all, there's nothing I like about you, I've never liked you, I'll never like you again'. And then five minutes later I'm like, 'You look really good in those jeans'.
''And then two days later he's helping me off the ledge and telling me things that only he could tell me because he's known me that long. And then the next day I want to stab him with a fork. So yeah.''
