“It’s kind of cliché but communication is the biggest thing in a relationship,” the multitalented 98 Degrees member tells PEOPLE Now. “You have to talk, you have to express yourselves. You don’t want to look back and resent not being heard.”
Though there’s no doubt they have a strong relationship after five years as husband and wife, Lachey, 43, reveals, “I don’t think there’s necessarily anything that’s rock solid about any marriage.”
“It’s always about that balance, especially when you have kids,” he adds.
He and Vanessa, 36, tied the knot in 2011, and the two welcomed their third child, Phoenix Robert, last month. They also share daughter Brooklyn Elisabeth, 2, and son Camden John, 4.
Despite keeping busy as a new dad to three, Lachey recognizes the importance of “spending time with the kids but also carving out the time for the two of you.”
“It’s important you spend time together just the two of you, but family’s everything so it’s important to spend time with the family.”
