Kelly Clarkson is excited to officially become a stepmother.

The 'Stronger' hitmaker, who is set to marry her fiance Brandon Blackstock at the end of October in Nashville, Tennessee, really enjoys looking after his two children from a previous marriage but admits she can be strict.

The 31-year-old singer said: ''I have a 12-year-old and a 6-year-old now ... after being single for six years! 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.''

Meanwhile, Kelly is too busy touring with Maroon 5 and preparing her new album to enjoy the final stages of planning her wedding.

She told Ryan Seacrest on his KIIS-FM radio show: ''It's two months away. It's end of October. I'm so over it. 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.''
