'Teen Mom Farewell Special' Sneak Peek: Catelynn Finds The Perfect Wedding Dress

With JWOWW, Snooki and Kristin Cavallari all planning trips down the aisle, no one can say the ladies of MTV aren't into commitment, and it looks like Catelynn of "Teen Mom" will soon join the order of matrimony, as well. In the sneak peek of the show's "Farewell Special" below, you can practically feel just how vested the soon-to-be Mrs. Baltierra is in her wedding ceremony, and when she finds the perfect dress, the waterworks commence. Still, as she and Tyler sit down to cake-test, they notice one thing missing from the day's agenda: Carly.

After Tyler and Cate consider incorporating a symbol representing Carly into their cake, conversation shifts to whether the little girl's adoptive parents will allow her to be present. "They didn't even want to come to our graduation," Catelynn says when Tyler expresses hope that Brandon and Teresa might consider accepting their invitation. "There's no way they'd come to our wedding."
