"My son is wonderful. He is amazing!" the Reem Acra-clad actress, 32, told Us Weekly at the Real Steel premiere in Universal City, Calif. Sunday. "Motherhood is a joy! I have dreamed about being a mother since I was 12 years old and there's nothing disappointing about it."
Lilly added that being a first-time mom is "actually more incredible than you can imagine. I think everything I say about motherhood sounds so cliche, but it's true."
Though Lilly has yet to reveal her son's name, the Canadian star told Us she's eager to expand her brood with Kali. "If I wasn't working right now, I'd probably be pregnant again!"
