The 43-year-old, who has presented the BBC contest alongside Bruce Forsyth since its first series in 2004, declared that she could not be lured away at any price.
"It's genuinely never about the money for me," Metro quotes her as saying. "To have money is a bonus in life and affords you luxuries.
"But Strictly is a job that I love and could never leave. It's a part of my life."
Forsyth has also recently spoken about his future on Strictly Come Dancing, saying that he "will know [when] it's time to retire".
"I've always told [my family] if I look as though I'm over the hill, you know, just tell me - but I think I'll know myself," he said.
Strictly Come Dancing's tenth series launched last weekend with a peak of 9.8 million viewers.
