Sofia Vergara spilled a few details about what she and fiancé Joe Manganiello have planned for their upcoming nuptials while walking the red carpet on Sunday night at the Screen Actors Guild Awards.

The "Modern Family" star wore a stunning, red Donna Karan gown and showed off the massive diamond that Manganiello placed on her ring finger over the holidays.

"It's all about the bling-bling, so he knew what I needed," Vergara told Access Hollywood.

Of course, she would have said, "Yes," no matter what the size or cut of the engagement ring. It also didn't hurt that her fiancé is drop dead gorgeous.

"I opened it up and I checked it to see," she joked. "He's so handsome that it would have been okay, you know? I would have said, 'Okay, yeah.'"

Due to their busy schedules, the couple will likely wait until the fall to exchange their vows. The "True Blood" star will have "Magic Mike XXL" premiering this July and Vergara's new movie "Hot Pursuit," co-starring Reese Witherspoon, opens on May 8.

"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," Vergara told Access Hollywood. "Summer is going to be too crazy."

The couple will also have to work around their TV schedules. ABC will likely renew "Modern Family" for a seventh season and Manganiello will star in the new Fox series "Scream Queens" from Ryan Murphy this fall.

Vergara also dished about the size of their wedding and the guest list has already ballooned from a small party of 20 to a much bigger shindig.

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