Hilary Duff Luca dog park Hilary Duff Luca dog park

On Saturday Hilary Duff brought her darling son Luca to the dog park in Los Angeles and the 26-year-old singer/actress introduced him to several pups running around.

Hilary lost her beloved Chihuahua Lola back in June, so we're wondering if she's thinking about adding a new member to her family. But we're talking about a dog, not a kid, and apparently there's a rumor going around the Hil and hubby Mike Comrie are planning for a second child!

Yesterday she tweeted, "I love that I do an interview &people ask if I want more kids.. I say yes. Not now thought and all if a sudden I'm "trying" for a girl. WHAT? It's ridiculous....The only baby I'm working on is my album."

That's the first we're hearing of it, but we're glad she cleared the air!
