Sofia Vergara debuted her large engagement ring from fiancé Joe Manganiello at the SAG Awards, where she also wore a red Donna Karan Atelier gown.

She opened up about wedding planning, saying they have to coordinate around his shooting schedule for Magic Mike this summer and hers for Don’t Mess with Texas with Reese Witherspoon.

As a result, they’re going to aim for a fall wedding.

"We're trying to figure it out because… he's shooting and promoting Magic Mike this summer and I'm promoting my movie with Reese Witherspoon and so we're kinda busy, but we're trying to do it maybe [in the] fall,” she told Access Hollywood. “Summer is going to be too crazy."

She continued to say they’ve already started making the guest list and admits it’s going to be “big.”

"It's big. We started, like, 'It's only 20.' Yeah right! It's like now there's like pages and pages," she said.

Manganiello and Vergara got engaged while in Hawaii over the holidays.
