Last month, Pink opened up about her husband in a candid Instagram Live chat with her therapist Vanessa Inn, sharing that couples therapy has been the key to the success of their 14-year marriage.

"I got a lot of s— for telling people that Carey and I have been in couples counseling with Vanessa," Pink said. "So I talk to Vanessa on my own and I also talk to Vanessa with Carey and for Carey and I. It's the only reason that we're still together because you know, I think partners after a long time, we just speak — I can't say it's a man and woman thing, I think it's a partner thing, a spouse thing — that you just speak two different languages."

The mom of two went on to say that "without Vanessa translating for me for the last 18 years, I mean, we would not be together."

"We just wouldn't because we are not taught as kids how to have relationships, how to get along with people," the singer added. "I mean, what's happening in our country right now is a perfect example of that. We don’t know how to love each other, we don’t know how to get along, we don't know how to communicate.”

Meanwhile, Hart wrote: "14 years married to this amazing woman. I'm so proud of the life that we have built together. Both of us came from broken homes, yet we made the choice to work hard at our relationship. And look at us now! Two misfits when we met, we have grown together and now have an amazing family."
