Hilary Duff's Baby Bump Begins To Show After Gym

Is that a baby bump we see?

A preggers Hilary Duff hit the gym with her older sister, Haylie, in El Lay on Tuesday afternoon.

She wore a grey t-shirt that allowed periodic glimpses of what looks like a growing baby bump!

Hilary also seems to enjoy yoga, which other pregnant celebs like January Jones and Alyssa Milano have enjoyed throughout their entire pregnancy, so we hope she sticks with it!
