The Girls Aloud babe notched up an impressive 40 points, a perfect score with 10 points each from the judges for her Tango and Cha Cha mashup.
Speaking on It Takes Two last night, Kimberley confessed: “I’ve been on a high all week, I still can’t believe it, it definitely happened?
“I knew that I had thoroughly enjoyed the dance and we might beat our 34 points!”
Kimberley’s pro dance partner Pasha Kovalev added: “I didn’t really expect it, I couldn’t believe it.”
This weekend will see Kimberley taking on two routines, an American Smooth and Charleston.
“It’s really, really hard to learn two dances in such a short space of time, but we’re getting there,” she said. “I love the American Smooth, it’s amazing and the song, I’m excited for it. The biggest challenge has been getting the mood, you’re concentrating on so much on doing things right that you lose the connection.
“The Charleston is so much fun, it’s such a great dance and you can jut get into it and enjoy it. We’ve got quite a few tricks which will be scary!”
She added: “We’re going to give it our best shot, we’d love to make it to the final.”
Strictly Come Dancing continues this weekend with the semi-finals on Saturday 15th December at 6.30pm with the results show on Sunday 16th December at 7.30pm on BBC One and BBC One HD.
