Martha Stewart, Corbin Bleu and Amy Purdy Are Ready to Say Yes to the Dress

Say Yes to the Dress

is bringing some star power to the new season.

Martha Stewart, Corbin Bleu, Dancing with the Stars‘ runner-up Amy Purdy and Miss USA 2014 Nia Sanchez are all stopping by Kleinfeld for season 14, and PEOPLE has an exclusive first look.

In the footage, Bleu looks on as fianceé Sasha Nicole Clements hunts for the dress of her dreams.

“I’m actually nervous, and I don’t get nervous,” he says, before seeing one of her choices, which he calls “absolutely stunning.”

The upcoming episodes also feature a new theme song written by Sugarland’s Kristian Bush, who visits the store during the season. Take a listen in the video above!

Say Yes to the Dress returns March 4 at 9 p.m. ET on TLC.
