Melissa Joan Hart and Mark Wilkerson have had to work "really hard" on their marriage in recent years.

The 48-year-old actress is married to musician Mark Wilkerson and has Mason, 18, Braydon, 16, as well as 12-year-old Tucker with him and explained that "new problems" have arisen as their children have grown and they have had to "come to a place of understanding" with each other.

She told Fox News Digital: "I think with every couple, as you get into new stages with your kids, you find new problems that you would solve differently than the other person would.

"I do think that Mark and I have -- we've really had to come to a place of understanding: Do you want to be right or do you want to be in [a] relationship?

"We really are a team. That's not always been the case, but we've worked really hard the last few years to be on the same team and to let the kids understand, 'You can't go to dad with something when I say no, and vice versa, because we're on the same team.' And it's no longer like, 'I don't know, go ask your dad.' Now it's, 'I'm going to check with your dad, and we'll get back to you."

The former 'Sabrina, the Teenage Witch' star knew instantly when she approached him at a gig as if she was a fan that it was "love at first sight" and they would end up married.

She said: "I went up there, and I met the band. And I saw this really handsome guy. And I went to my publicist who happened to be in the room and said, 'I need to meet him.' And she goes, 'Oh, we're already on it.'

"He came out front after, which he would normally -- now I know -- he would have normally gone back, gotten on his bus and, you know, gone back to the hotel for the night and performed the next day [in] the next city. But he stuck around.

"He walked past my table three times, and I had to stop him.

"We chatted for a few minutes, took a picture together. And then I went back to his bus, met his mother, said goodbye. He drove off.

"Three days later, I called his tour manager!

"Then we went down to Alabama, saw where he lived and grew up. He performed in, I think, Tampa. We flew to San Francisco. His tour bus drove me down to LA, dropped me off after a show at The Palladium, and, like, a week later, I was miserable without him. And I jumped on a plane and went to spend the rest of my summer with him.

"And seven months later, we were engaged.

"I would say it was love at first [sight]. I mean, I literally even told someone the next day I met the man I'm going to marry."
