Though the Hollywood stars have been through some ups and downs, the 7th Heaven alum revealed the secret to their marriage.

"I'll have to give Justin the credit in this moment, for this one thing that he always says to me: 'We might be married, but we have to keep dating,' and it's so true," the brunette beauty previously shared in an interview about her man. "You just have to keep making time for each other and you have to keep making each other a priority. And do the things that you love together. It's not always easy, as we all know, but those touch point moments make all the hard times palatable."
