"For me, [I'm most proud of] the growth [of our relationship]," Spelling revealed. "It just gets better, and I think when you go into a relationship, at least for me, you have all these fairy tale expectations. What it should be or shouldn't be, where it's going to go and where it's going to plateau. You get to that point where [it's like], 'Wow, this is amazing' on a different level of what I ever expected."
"In our relationship, we've definitely had to, not start over, but rebirth the relationship as something that was new and kind of moving on towards the future." she continued. "By doing that, we've had this great, amazing rebirth of our relationship, and it's more exciting each day."
McDermott chimed in, saying, "Our relationship is in the best place it's ever been."
"I was just thinking about it in the car ride over here, about how grateful I am and how filled with gratitude I am that we're still together, and my life is wonderful," he added. "I have these wonderful babies with you. I have this wonderful life with you. I'm so grateful and happy."
The lovebirds have four children together -- daughters Stella, 7, and Hattie, 4, and sons Finn, 3, and Liam, 8. McDermott is also dad to another son, Jack, whom he shares with his ex-wife, Mary Jo Eustace.
Last November, Stella and Hattie made their modeling debuts in a campaign for Modern Queen Kids. Press play on the video below to see them all glammed up in their adorable (and very glitzy!) photoshoot.
