Kelly Clarkson may be a global celebrity, but it seems she's no different than many mortal women -- because the engaged singer has officially had her fill of the whole "wedding planning" thing.

"It's two months away. It's end of October. I'm so over it," she told Ryan Seacrest about her upcoming nuptials to fiance Brandon Blackstock. "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."

Kelly may not be a wife yet, but the 31-year-old star has already seamlessly moved into the role of step-mom to Brandon's two kids (a 12-year-old girl and a 6-year-old boy).

“We all live together and everything ... it’s so different, but it’s perfect," the star explained. "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.”
