Harris, who played tawdry high school cheerleader Rachel Gatina on One Tree Hill, shared a picture from their outing via Twitter Jan. 20. "Happy Sunday," she wrote in the caption. The 33-year-old showed off her tiny baby bump in a loose-fitting printed blouse.
"It's a great pat on the back that they moved us out of Friday -- which, you know, we were doing fine, it's just a really tough time slot. And a lot of times, it can be considered the night that shows go to die. So not only did we not die, we survived and we grew and I think that that's a big testament to the fans and how supportive they are and how loud they can be about our show," Ackles, 34, told The Huffington Post in 2012.
Harris accepted Ackles' proposal in 2009 after a three-year courtship. The couple married the following year in the actor's hometown of Dallas, Texas.
