Jackson Rathbone has been busy doing press for the final Twilight movie, but there’s something else that’s taken up even more of his busy schedule — baby Monroe, 4 months!

The Breaking Dawn: Part 2 hunk stopped by Kathie Lee & Hoda for the fourth hour of Today and opened up about his baby boy, who is just adorable!

“It’s so fun watching him learn every day. The other day he was looking at his hand like a college kid on mushrooms like ‘woah, look at that man,’” the actor joked.

But he wasn’t prepared to be so enamored with everything his little guy does — even the dirty diapers!

“It’s the sheer joy…and incredible fascination of everything he does,” Jackson said, “I have pictures of his first poop. I called all my friends and texted them ‘my son’s first poop!’”

TMI! But there’s no denying his baby boy, whom he welcomed in July with girlfriend Sheila Hafsadi, is super cute. Luckily, Jackson brought photos to share — check them out below!

We’re all waiting impatiently for Breaking Dawn Pt. 2 to hit theaters this fall. One reason for our excitement is to see Kristen Stewart and Robert Pattinson in action as parents. In a new interview, their co-star Jackson Rathbone gives us an idea of what that will look like.

“It’s really cute. It’s endearingly awkward at moments, to be honest,” Jackson told Celebuzz at the final Twilight Comic-Con panel on July 12, before adding, “Maybe that’s just off camera…”

All kidding aside, Jackson continued, “It’s [going to] look great, it’s [going to] be great. They’re so sweet. They’re all fantastic actors.”

During the interview, Jackson, who welcomed his first child into the world on July 5, also spoke heavily about how the cast has become such a family. He talks about feeling like Kristen is his sister and even refers to our favorite couple as “Uncle Rob and Auntie Kris” when discussing bringing them around his son. Watch the full interview below!

What do you think, HollywoodLifers? Do you think Rob and Kristen are endearingly awkward or just endearing?

Robert Pattinson and Kristen Stewart have one of the greatest romances of all time, and their Breaking Dawn co-star admits that it is totally enough to carry an epic and expensive franchise!

Rob, 26, and K-Stew, 22, totally deserve to make a fortune off of the movies, their costar Jackson Rathbone tells popular video podcast Last Week On Earth with Ben Gleib.

“I don’t do half as much — or even a fifth as much — work as Rob, Kristen or Taylor [Lautner] in those movies,” he admits. “They were on set every day 24/7. [Kristen] definitely deserves [her wealth].”

Do YOU think Rob and K-Stew’s romance is worth millions, HollywoodLifers?

Kristen Stewart‘s boyfriend Robert Pattinson isn’t the only one singing her praises, her Breaking Dawn co-star Jackson Rathbone thinks she’s amazing, too! HollywoodLife.com spoke to Jackson, 27, at the LA premiere of Man On A Ledge and he says Kristen kicks major butt as a vampire in Breaking Dawn!

“You finally get to see Bella realize herself as a vampire,” he tells us. “And that is fun for everybody. You know she is such a powerful force. Kristen really brings this animosity to Bella that we haven’t seen during the course of these films. It is really exciting to see Kristen step up and really bear her teeth, so to speak.”
