It's the first baby for the Pretty Little Liars: Original Sin star and his wife, who tied the knot in 2018 in a ceremony overlooking the ocean in rural Gualala, California. The couple attended UCLA together, according to Playbill.

The actor and his wife announced their exciting pregnancy news on Instagram in April.

"Baby K, you're about to light up our life in a big way! 💙Sept. 2022💙," Klena captioned the Instagram slideshow, which features a photo of him giving his wife's pregnant belly a smooch at sunset as well as a picture of the pair holding a sonogram.

In a post honoring Elycia on her birthday last December, the former Jagged Little Pill star got candid in his caption about all the little things he loves about his wife, accompanying it with a picture of her in a colorful strapless top and rose-tinted circular sunglasses.

"Happy Birthday to the most incredible partner, friend, sibling, daughter, auntie, travel buddy, book lover, and mother of dragons anyone could ever ask for," Klena wrote. "You amaze me with your beauty every day, both inside and out. Here's to many more bdays by your side ❤️🥂."
