Hayes MacArthur Ali Larter baby sweater dress tan pants easter

Adorable!

Ali Larter and her hubby Hayes McArthur took their precious baby son, Theodore Hayes MacArthur, out for his very first Easter dinner on Sunday.

The little guy was born Dec. 22, and since then Ali has been on full-time mommy mode with baby Hayes, but she still manages to stay in perfect shape.

The Heroes star said in an interview: "From the morning through night, I just wear my workout clothes so that if I can grab a half an hour here or there then I'm ready to go. Being a new mom, my time is of the essence."
