"I just watched you look at Tori taking pictures, and you were looking at her like, 'That is my woman, and she is looking good!'" ET's Deidre Behar said.

"You did catch me doing that," he admitted. "She's amazing. She's stunningly hot!"

Spelling, who was standing right next to her beau during ET's interview, started blushing as McDermott continued to compliment her.

"I'm the luckiest guy in the world," he added. "I have a super-hot wife."

McDermott, 49, and Spelling, 42, will celebrate their 10-year wedding anniversary in May.

Despite past infidelity and marriage woes, the pair is going strong. Spelling told ET that the thing she's most proud of is "the growth" of their relationship.

"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."
