Denise McCormack believes bookies' outsider Des Cahill is her biggest threat on Dancing With The Stars.
Starting the competition as an underdog, the sports presenter has sailed through the first nine weeks to land himself a spot in the final five. And McCormack fears Cahill could stop her from grabbing the glitterball trophy.
With the finish line in sight, Denise admits the RTE star is a real crowd favourite.
"The public adore him and rightly so, he is brilliant, he's good fun and entertaining. He's really pushing himself," she told the Herald.
"Everyone is pushing themselves to the very end. Everyone is upping their game and putting in the hours. It's an interesting one."
The cast members celebrate in Bray after each week's performance but sensible Denise has had to miss out on most of the nights out.
"We usually have a drink after the show in Bray and hang around together and then everyone goes into town, but I live in Bray and I've got the school run the next day as well and I can't really be hungover doing that. I'll pick a few nights to let my hair down, definitely the final," she said.
The former Love/Hate star likened the competition to a "marathon" and has found gruelling rehearsal sessions draining.
"I have a bit of a routine to make sure I get enough sleep and eat the right things. It's about being disciplined in your life and it's hard to maintain that. It is like a marathon," she said.
"It's a sprint towards the end but you really feel like you're sprinting from the beginning. It's always about pushing it to the extreme. It's physically and mentally draining."
The Red Rock actress has received an outpouring of goodwill from fans of the show. "Everywhere I go, people say congratulations, keep up the good work," she said.
