Speaking to HELLO! and other outlets, the former Coronation Street actress described the late Love Island host as one of her inspirations out of the show's past contestants.

The pair danced sensationally together throughout the entire series, culminating in an emotional showdance to Angels.
Caroline tragically died by suicide at the age of 40 last February.

"I'm looking for somebody who's fun, who knows what they're doing," she revealed. "I want to work hard and I really do want to learn how to dance, but I want to laugh along the way.

We can't wait to see what happens on the launch show and who's paired with who, and this year will make history with the first all-male pairing.
