Let the countdown begin! Haylie Duff isn't slowing down at all in her third trimester. The Real Girl's Kitchen host was spotted running some errands — and showing off her growing baby bump — in L.A. on Wednesday, April 8.

Duff, 30, wore loose-fitted jeans for the sunny outing with a white tank top and cardigan. She went makeup-free and kept her blonde locks up in a messy ponytail.

Hilary Duff's big sis announced last April that she and fiancé Matt Rosenberg are engaged. Getting ready for their first child (a baby girl!), the couple celebrated with a star-studded baby shower last month.

Duff received plenty of pink items at the bash, but has also been purchasing onesies and booties for her daughter too. To top it off, she shared a sweet photo of the parents-to-be via Instagram on Tuesday. "30 day countdown!" she gushed.
