Kelly Clarkson had a ''breakdown'' over her wedding plans earlier this month.
The 'Stronger' singer - who got engaged in December - has admitted she is terrified ahead of her upcoming nuptials as she and fiance Brandon Blackstock are already struggling to keep their guest-list under control.
The 30-year-old 'American Idol' winner told California country radio station K-Frog: ''We're just kind of overwhelmed with the planning of the wedding. We're actually thinking fall this year and we're thinking outside. We're trying to make it small, but it is hard. I literally had a breakdown two weeks ago about the wedding list.
''I'm terrified of everyone watching me walk down the aisle.''
Shortly before getting engaged, Kelly revealed she had no idea about what kind of wedding she would want and would probably elope.
She said: ''Honestly I've never been the girl to plan a wedding. We will totally, probably elope.''
The singer previously called her relationship her ''best accomplishment'' after years of being unlucky in love.
She said: ''I completely fell in love. I did! Welcome to Cheeseville! I don't know. Your priorities kind of shift and you become happier and all that stuff. It's probably my best accomplishment because I think, for me, especially, I just didn't think it would happen.''
