Life is imitating art for Army Wives star Catherine Bell!

Like her character on the hit Lifetime show, the 42-year-old actress has also been on diaper duty since welcoming son Ronan on August 21, 2010.

"He's the happiest baby ever!" Bell tells the new issue of Us Weekly (on stands now). "He's so easygoing. As long as he's fed and entertained, he's good to go."

And the actress, who also has a daughter, Gemma, 7, with actor husband Adam Beason, 41, tells Us it's too soon to tell if "he's mommy's boy or a daddy's boy."

"His heart belongs to her sister," she says. "He's only got eyes for her!"
