And we're not just referring to Hilary Duff's Bernese mountain dog Dubois.
In a snapshot she posted Sunday, Duff's son, Luca, 19 months, photobombs this otherwise canine-focused shot of her house (sans the rest of her puppy pack).
"I spy a little luca," she writes on Twitter.
As for Luca, he might find himself with a little brother or sister in the future.
“If I had another boy, I would be happy, but I would like to try for a girl," Duff, 26, told reporters last month. "And I’m not sure that I want to have three kids."
