'The Walking Dead' alum Steven Yeun expecting second child

Dec. 5 (UPI) -- The Walking Dead alum Steven Yeun is going to be a dad of two.

The 34-year-old actor is having another baby with his wife, Joana Pak, who announced the news Monday on the couple's second wedding anniversary.

Pak showed off her baby bump in a mirror selfie on Instagram and captioned the photo with family emojis. She and Yeun are already parents to 18-month-old son Jude Malcolm.

The Walking Dead star Norman Reedus and showrunner Angela Kang were among those to congratulate the couple in the comments of Pak's post. Reedus commented with four red heart emojis.

"Yay! So cute!" Kang wrote.

Yeun had called Pak an "MVP" while celebrating her birthday in October. He posted a photo of Pak sharing a moment with their son on a busy sidewalk.

"happy birthday to the mvp," the star wrote, adding a heart emoji.

Yeun played Glenn Rhee in Seasons 1-6 of The Walking Dead and was killed off in the Season 7 premiere. He said in an interview with Slate in October that he felt "cramped" as an Asian-American actor in the role.

"It's like: nice guy, dependable, supportive, benign. Beige," the star explained. "That was a little bit of the frustration that I could never explain to the wider society, to fans of the show."

"I felt like there wasn't enough space for me to fully spread all of who I was, and that was partly due to me, too, because when I started, all I was trying to do was to work within the parameters that they were giving me," he added. "And then, over time, I just outgrew it."
