The cuteness is UnREAL! Shiri Appleby and her fiancé, Jon Shook, have welcomed their second child together — a baby boy. The Roswell alum announced the news via Instagram on Monday, December 21.

"Glad to welcome home Owen Lee Shook," Appleby, 37, captioned a sweet family photo. "#5daysold #alreadycrackingjokes #1800gotaboy."

The proud mom of two appeared to be on cloud nine while posing with her growing family. Shook, 34, held little Owen as he smiled alongside the couple's 2-year-old daughter, Natalie.

Us Weekly broke the news in August that the UnREAL actress and the L.A. chef were expecting baby No. 2. "…and then there were four," she captioned an Instagram pic of her baby bump at the time.

Last year, Appleby opened up about balancing work and motherhood. "Being a woman who is trying to parent, be in a relationship and manage a career is still a work in progress, but it's working for me at the current time," she said, via The Huffington Post. "I am enjoying it more than I ever thought possible — quite frankly, I've never been so fulfilled."

Appleby and Shook began dating in 2010 and got engaged during a romantic Italy getaway in July 2012.
