Boston Marathon Bombing Victim to be on “Say Yes to the Dress” Finale

"Say Yes to the Dress" finale premieres tonight and will feature a very special guest.

TLC's "Say Yes to the Dress" will feature a Boston Marathon survivor on its season finale, which airs tonight at 9pm.

Rebekah DiMartino, 27, was watching the 2013 Boston Marathon when the two bombs exploded next to her, only a few feet away.

After 30 surgeries since that day, doctors amputated DiMartino's left leg below the knee. Since then, she has had a prosthetic leg developed for her and is training for the 2015 Boston Marathon bombing.

Now, a year and a half later, DiMartino is married to her husband Pete, who was also hurt in the bombing.

After being chosen to win a "dream wedding contest" on TheKnot.com, visitors on the site helped DiMartino pick out her wedding dress, a Sophia Mancelli creation from Kleinfeld, one of the upscale bridal salons in New York City.

Despite the difficulties facing her, DiMartino was determined to find and try on the perfect dress for her wedding day.

Trying on the dress itself was a difficult obstacle for DiMartino. "Actually trying on the dresses was one of the most physically exhausting things I have ever done," DiMartino said. "I almost passed out from the sheer pain quite a few times, but I was determined not to let it stop me."

The wedding took place in Asheville, North Carolina at the Biltmore Estate.

This is going to be an episode that you surely don't want to miss!
