Ferguson had joked that at just 9 weeks old, a baby girl was still nice and wasn't running around yet.

Kunis and Kutcher welcomed Wyatt back in early October and the couple announced it on Kutcher's site Aplus.com.

"Mila and I would like to welcome Wyatt Isabelle Kutcher to the world. May your life be filled with wonder, love, laughter, health, happiness, curiosity, and privacy," he wrote.

According to E! News, Kunis added last night on "The Late Late Show" that she looks great only weeks after delivering because "Breastfeeding's a great workout!"
