Kelly Clarkson hasn't even said "I do," but she's already wishing her wedding was over.

Speaking with Ryan Seacrest on his radio show On Air With Ryan Seacrest Tuesday, Aug. 20, the 31-year-old bride-to-be complained about the difficulties of planning her October wedding to fiance Brandon Blackstock.

"It's two months away. It's end of October. I'm so over it," she shared. "It's so overwhelming. We're just doing a lot: touring and the wedding and the Christmas album, so I'm over the wedding part."

The American Idol winner became engaged to Blackstock in December 2012. Blackstock has two children from a previous marriage.

"I have a 12-year-old and a 6-year-old now... after being single for six years!" Clarkson said. "We all live together and everything... it's so different, but it's perfect. They're awesome and I actually really dig the mom thing... I am quick to go, 'I told you not to touch that!' ... I am totally my mom. My mom was a hard mom."

Listen to Clarkson's interview:

"Brandon's totally the one," Clarkson, 30,told Cosmopolitan for its February issue. "I've never been so happy."

After dating for a year, Blackstock, whose father Narvel Blackstock is Clarkson's manager (and Reba McEntire's husband), popped the question in December on what she called the "happiest night of my life."

Clarkson continued to gush about her beau. "We've known each other for years, but we didn't start talking until the Super Bowl last February," Clarkson said. "I've never been truly loved like I am right now."
