Hello baby bump! Kristin Cavallari showed off a first glimpse of her growing belly on Thursday. Confirming her pregnancy just two weeks ago, the former Hills star has already taken to Instagram to show off her lil' bump. Too cute!

Cavallari and husband Jay Cutler, who were wed in June, are the proud parents to 15-month-old Camden. And except for a slight bulge, you can barely tell the former reality star has a bun in the oven. Lookin' good lady!

The 26-year-old showed off fit form in gray leggings, black ankle boots and a dark gray T-shirt with the word "home" written on it. Kristin posted the pic with the caption, "Early holiday gift from @peoplestylewatchmag! Check out this @thehomet and more great gift ideas in the December issue on sale Nov. 22! A percentage of the proceeds from sales go to multiple sclerosis research :)"

Looks like KCav is proud of her bump and trying to help some people in need too. What a good mom!
