Catelynn Lowell And Tyler Baltierra Reveal Their Extra-Special Wedding Theme

The 'Teen Mom' couple is planning a blast from the past!

When Catelynn Lowell and Tyler Baltierra become Mr. and Mrs. later this year, the couple and their loved ones will journey wayyyyyy back in time to a whole different era.

The longtime sweethearts, who became engaged in 2010 during an unforgettable moment on "Teen Mom," have revealed details about their highly anticipated summertime nuptials -- and how they chose the look and feel for the formal affair.

"Our venue is a castle -- it's an old castle," Cate tells MTV News in the clip below about the Michigan location. "It's definitely like an old type of masquerade theme."

"We're going with like a Renaissance kind of thing," Ty chimes in.

Think back to the times of Shakespearean garb, jousting (like Heath Ledger bravely did in "A Knight's Tale") and Christopher Columbus sailing the ocean blue in 1492.

But back to TyLynn's big day. Have the duo made any other key decisions -- like the song for their very first dance as husband and wife? And how are they feeling about their wedding? Watch the video below, stay with MTV News for continuing "TMOG" coverage and be sure to catch Catelynn and Tyler -- along with Maci, Amber and Farrah -- on the show's season premiere on Monday, March 23 and 10/9c!
