Emmy Rossum

Emmy Rossum said yes to the dress!

The Shameless star revealed to E! News exclusively that she tapped renowned designer Carolina Herrerato create what is sure to be a most stunning gown.

"You'll find out tonight," the bride-to-be initially teased at An Evening Honoring Carolina Herrera in New York City Tuesday evening, before adding, "Yeah, she'll be making it. That's all I'll say!"

Emmy said, "Yes!" to Mr. Robotcreator Sam Esmail in August 2015, and after shooting down marriage speculation over the summer, it looks like the actress and her leading man are closer than ever to the big day!

And given Rossum's gorgeous wardrobe, it's no wonder Herrera has the honor of dressing the actress before she walks down the aisle.

After wearing Carolina Herrera at the New York Botanical Garden's 2015 Conservatory Ball, Emmy thanked the fashion mogul on Instagram for the glam look. "Look at how fabulous she is, like a fashion fairy godmother watching over to be sure the fit is perfect! She is kind, elegant, wickedly funny and I'm lucky to call Carolina my friend," Rossum wrote.

She also attended Carolina's New York Fashion Week show earlier this year.

Last fall, Rossum played coy about her wedding plans during an interview with E! News' Marc Malkin:"We're just chilling for a hot second. I'm not even answering my family who asks me. I know everything. I'm just not sharing it. I'm honestly just chilling and enjoying it for now."

Emmy, 30, and Sam, 39, started dating in 2013 after casting her in his directorial debut, Comet.

Congrats, Emmy! We can't wait to see the final look.
