hasn't forgotten about the other kids in the house!
Though the actress and husband Mike Comrie became parents to son Luca on March 20, she was already a mom of sorts to her pack of dogs
– Yorkie Jak, Chihuahuas Lola and Coco, and Bernese mountain dog Dubois – and she still has her eye on them.
"Where's Jak???" she Tweeted
on Monday, along with a seemingly nondescript photo of a couch and two pillow cushions.
Upon closer inspection, Jak was blending in totally with his surroundings and nestled between the two pillows. Luca, get ready to play some hide-and-seek!
