EXCLUSIVE: Daniel Gillies Gushes Over 'Beautiful' Wife Rachael Leigh Cook, Reveals If Baby No. 3 Could Happen!

Daniel Gillies is perfectly happy being a father of two!

The Originals star stopped by the ET studios on Friday for a live interview and opened up about what life is like with his "beautiful" wife, Rachael Leigh Cook, and their two children, Charlotte, 3, and Theodore, 2.

"There's a lot of snatching of toys going on," the 41-year-old actor revealed with a smile.

"But [Charlotte] is a very sweet, older sister to him and she's day-by-day becoming more and more demonstrative," he said. "She'll be really sweet to my son and be like, 'Look, Daddy! Look at how great I'm being,' so that she can receive the reward later on, which is that I have to play her episodes of Dora the Explorer."

"If you're not a parent, you'll get to know Dora, trust me," he added with a laugh.

Cook, who is best known for her role in the beloved 1999 teen rom-com She's All That, tied the knot with Gillies in 2004, and the CW star confessed that after 12 years of marriage, he still "can't believe how beautiful" his wife is.

"This is going to sound like the creepiest thing of all time," Gillies prefaced his tale, "but when I was first married her… I remember just watching her sleep and thinking that is the most beautiful person and I would just watch her for a while." Aww!

"It's also amazing to see when our kids have inherited some of her physical characteristics," Gillies shared.

So can we expect to see a third baby join the Gillies family? "No!" the New Zealand native laughed. "Daddy is going to pay a special visit to a special surgeon real soon."

"I'm too old as it is. My wife has got the energy of a 21-year-old and is physically in great condition, but me, I have, like, no knees and no shoulders," he continued. "But no, that's the answer. I want to be able to give these two my love and my attention and my care. I would like to stop now."

While Gillies isn't ready for another baby, he is ready to expand his resume. In addition to reprising his role as Elijah Mikaelson on the fourth season of The Originals, Gillies also had the opportunity to step behind the camera as the director of an upcoming episode.

"It was something that I had wanted to do and it was something that I had seen [my Originals co-star] Joseph Morgan do in the season before, so I was immediately and violently jealous. I thought, 'Well, I've got to do that,'" he explained jokingly adding: "And then Charles [Michael Davis] got signed up and I thought, 'Well, if that hack is going to do it, now I've got to jump in.'"

Gillies confessed that watching the directorial debuts of his two Originals co-stars taught him a lot about the process. "I learned a tremendous amount about what not to do, particularly from Joseph," he teased.

As for the most difficult actor to direct on set? Gillies revealed that there was one person who was a complete monster to work with.

"I would say me. I'm just so resistant to direction," he deadpanned. "I didn’t realize what an a**hole I was to direct until I directed me and I was like, 'Oh! This is why everyone has got a problem with me!' Like, I'm the worst. Why am I contesting every line? I'm like, 'Oh, my character wouldn’t say that,' and then I had to come back to the monitors and yell at me."

The Originals airs Fridays at 8 p.m. ET/PT on The CW.
