In this exclusive clip for the new season of Say Yes to the Dress, Jillian Michaels surprises former The Biggest Loser contestant Tumi Oguntala, and their reunion is a tearjerker.
Oguntala, 42, who lost 175 lbs. on season 15, reacts to Michaels as if she's seen a ghost and then breaks down at the sight of her former trainer.
"In all my 20 years working at Kleinfeld's, I never witnessed something so emotional," says bridal consultant Debbie Asprea.
"I'm so happy [Jillian]'s here," says Oguntala. "She's been such a big part of my life for so long. Just that she would show up for me today like she always does. I'm just very moved, very touched."
Oguntala lost her mother to cancer when she was 14, and has said the loss made her "scared to start a family because of the fear that I, too, would leave young children behind."
Now, Oguntala is ready for marriage, and her special bond with Michaels has given her the support she needs.
"I said I'd always be here when you need me," Michaels tells the former contestant. "Seeing Tumi today is magical for me."
Season 12 of Say Yes to the Dress premieres Oct. 10 (9 p.m. ET) on TLC.
