EXCLUSIVE: Host Jimmy Kimmel Previews What to Expect From the Emmy Awards

The celebrities can take a deep breath. Jimmy Kimmel says most of TV's biggest stars will be spared from his caustic wit at the Emmy Awards on Sunday.

"There are a few that maybe should be a little bit worried, but for the most part everyone can relax," Kimmel told ET.

Among those who are safe are the newly broken up Taylor Swift and Tom Hiddleston.

"I think it's a little bit weird when somebody goes through a breakup and suddenly they're on camera and everyone's making fun of them," Kimmel explained. "It's a strange thing -- one of the strangest things about Hollywood."

ET caught up with Kimmel as he got decked out in a tuxedo to help roll out the Emmy red carpet outside The Microsoft Theater in Los Angeles on Wednesday.

The Jimmy Kimmel Live! host is looking svelte ahead of the big show, and he revealed his slim-down secret to ET.

"I decided, 'You know what I'll do? I'll stop eating on Monday and Thursday and we'll see how that goes," Kimmel joked. "I spend all day online looking at recipes."

Inside the theater, we got a look at where the stars will be seated. The Modern Family cast is tight-knit group, sitting together, while Amy Schumer has a seat up front. Beyonce will be nice and cozy in the second row as she hopes to win an Emmy for her visual album, Lemonade.

The 68th Primetime Emmy Awards will air live from The Microsoft Theater in Los Angeles Sunday on ABC.
