Season 3 of TLC's "90 Day Fiance" comes to close tonight, and audiences will find out who said, "I do" and who said, "I don't."
Zap2it got an exclusive clip from the episode, which features the young and in-love couple, Loren and Alexei, having some serious pre-wedding jitters. The stress really gets to Loren, and she takes it out on her mother, yelling, "What do you know? You and Daddy are miserable!"
Alexei, remains outwardly calm, but struggles to find the words to express how he's feeling. "Living with someone for 90 days, isn't really enough to know the person," Alexei worries.
Will Loren and Alexei make it down the aisle?
And then there's Carolina and Fernando. In this clip. Carolina is in tears -- skyping with her family before the big day -- saying, "I'm scared," honestly questioning whether or not she is making the right decision.
Will Carolina and Fernando tie the knot? What about the rest of the couples? Will the 39 year age gap between Mark and Nikki finally prove to be too much?
The season 3 finale of "90 Day Fiancé" airs Sunday, Dec. 6, at 9/8c on TLC.
Immediately afterward, “The Couples Tell All” special, featuring all 6 couples and hosted by NBC News' Erica Hill, will air 10 p.m. ET/PT.
