Jamie Lynn Spears is pregnant and officially engaged, all at the tender young age of 17 (as of this Friday). The actress was spotted wearing an engagement ring a little over a week ago, and since then fiancé Casey Aldridge’s cousin (and a few of Jaime Lynn’s friends) have confirmed the impending nuptials. OK! claims to have several exclusives on Jaime Lynn’s wedding plans – though of course we have to wait until it’s on newsstands for all of the specifics.

OK says Jamie Lynn will wait until after the baby is born to marry Casey. Her friends speculate that she’ll want to set the date several months after the birth so that she can get her figure back in order to wear her perfect wedding dress. There’s also a bit of talk about her dream wedding – though something tells me that in Jamie Lynn’s dreams, her wedding was never supposed to happen quite so soon – and probably not with her new baby at the ceremony.

The Zoey 101 star is expecting her first baby in late June with boyfriend Casey Aldridge, and is happily riding out the last months of her pregnancy with Casey by her side. After announcing her pregnancy exclusively to OK! in December, Britney Spears’ little sis has been busy lying low in her hometown of Kentwood, La. As OK! was the first to report, Jamie Lynn and a cousin recently registered for her baby shower at a Babies ‘R’ Us store in the nearby city of Baton Rouge.

And those closest to Jamie Lynn tell OK! the teen plans to stay true to her small-town roots, most likely exchanging vows with Casey in Kentwood at “Serenity,” the estate owned by Britney — who obviously leads the list of possible bridesmaids. “She’ll have the baby there, and soon after, she will also get married there,” says a pal of the teen. “I expect she’ll want to wait at least several months to get her figure back so she can wear a beautiful wedding gown and then have her dream wedding.”

You can’t help but worry for anyone who gets married at 17. And to be fair, you can’t help but worry for anyone who has a baby at 17. Putting the two together seems like a lot of pressure on such a young couple. They’re certainly better off financially than any other 17-year-old couple I’ve ever heard of, but money doesn’t equal maturity. Hopefully Jamie Lynn’s got a better head on her shoulders than some of her family members… or will at least hire a very, very qualified nanny.
