Bumpwatch is on! Just one week after Leah of "Teen Mom 2" announced that she's pregnant with her third child (her first with new hubby Jeremy Calvert), she and her blossoming belly were captured on film by photogs.

Yesterday, Leah took her two-year-old twins Ali and Aleeah to a park in their West Virginia neighborhood dressed in a fitted brown shirt-and-jeans combo that accentuated her growing mid-section. The cutie patooties enjoyed their fair share of slide action and fresh air with their expectant mama, who will give them a new sib this winter. And today, the tots spent some time outdoors with their stepdad. "Jeremy && the girls working on their .. I guess snowman? LOL," Leah tweeted before warming 'em up with some home cooking. "&&& now they're ready for mommys homemade chicken noodle soup!" she posted.

Get in all the QT--and tweets!--you can, Leah! Pretty soon, something tells us you'll have your hands very full.
