Katherine Heigl ‘Panicking’ About Wedding Details

She's got a Golden Globe nomination, a hit show and a successful move career. But there's still one thing that Katherine Heigl can't rest easy about: Her upcoming wedding!

“I'm mostly panicking about all the details, and getting there, traveling, transportation, talking to the pastor, getting the license,” Katherine confessed to “Extra.”

The beautiful “Grey's Anatomy” star is getting ready to wed musician Josh Kelley in Utah next week, but she admitted she and Josh are both suffering from pre-wedding jitters.

“We've talked a lot about it, like, 'Are you having any second thoughts here?'” she said. “And he's like, 'No, I'm so ready for this to happen.' It's already been 18 months of planning and we're both just ready for this to happen already.”

And once the wedding's over, she said she and Josh plan to have kids!

“I'm super excited to start a family,” she gushed. “I've always wanted a family, a large family. But I saw that now!”

How soon?

“I'd like to say like a year,” she said.

Ironically, the 29-year-old actress plays a young woman who's always the bridesmaid and never the bride in the upcoming “27 Dresses.”

“Yeah, that was really coincidental!” she said about filming the movie as she planned her own wedding.

And by the time the movie hits theaters on Jan. 11, Katherine will already be a married woman herself.
