We'd been wondering when HIlary Duff's baby bump would be a bit more visible!

Hil announced her pregnancy in mid-August, which means she's probably about five months along now. We hadn't seen much of a pregnancy protrusion yet, but we spotted a beautiful bump as Hil headed into pilates on Wednesday.

Indeed, Duff Tweeted on Tuesday, "Baby's getting big!" Cute!
