Ever since Katherine Heigl and husband Josh Kelley announced that they're expanding their adorable family with a third child, a boy, the couple has had a variety of supercute appearances out together. Over the weekend, they kept up their habit of looking giggly at a star-studded baby shower that Katherine's mom hosted for her in LA. In addition to family and friends turning out to wish her well, the actress also had the support of her Doubt costars, Laverne Cox and Dulé Hill, who posed for photos with her at the fun event. The party was decorated with trees and twinkly white lights, which Katherine revealed were inspired by her and Josh's "mountain home in Utah, where the baby will be born" on her blog. So cute!
