Jamie Lynn Is Pregnant, Y'all

We caught Jamie Lynn showing off her baby bump at a baseball game in Louisiana yesterday.

We're thinking she must have sold her story to OK! the second she found out she was preggers 'cause she's not looking too far along here!

She seems to have settled back in to "country" life, cheering on the local team and donning her old homecoming t-shirt. Life may be simpler there (than in LA), but being 16 with a baby won't be easy -- good luck, Jamie Lynn!
