Two moms-to-be, two very different-sized baby bumps. Hilary Duff, who's eight-months pregnant and expecting a son next month, stepped out on Thursday looking adorably chic in a yellow blazer, tight cotton top, patterned scarf -- and towering high heels -- for a doctor's appointment. "Baby's looking perfect!" she gushed to her 900,000-plus Twitter followers. "So it's a great day..except for my ribs..which get a good solid kick every half hour!" In a follow-up tweet, Duff posted a pic modeling her Rag and Bone outerwear. "It's the color of sunshine!! It just doesn't close right now! Lol! Temporary!" Duff, 24, said she planned on wearing tight clothing throughout her pregnancy to proudly show off her bump, and she has stayed true to her promise whenever she's out and about.

Still in her first trimester, Kristin Cavallari took the opposite approach in a loose-fitting nude-colored jumpsuit in Los Angeles the same day Duff was out. Just the night before, the onetime "Hills" star debuted her itsy-bitsy baby bump in a red mini at the premiere of Reese Witherspoon's "This Means War." Cavallari, 24, who's engaged to Chicago Bears quarterback Jay Cutler, gushed about her big moment afterwards on Twitter. "Here is a pic from last nights premiere and you can see a little baby bump," she posted.

As for Cavallari, she has put all wedding planning on hold to focus primarily on her baby. "I'm not even looking for a wedding dress right now," she recently told Celebuzz. "I'm pregnant! I'm not going to go try on wedding dresses." But she is still keeping an eye on her expanding shape for when the time does come to walk down the aisle with Cutler. On Friday, the "Dancing With the Stars" standout tweeted about working out with her personal trainer, John Damon, writing, "Best way to start the day!"
