Radio One DJ Sara Cox has revealed she was worried about fitting into her dress for the Strictly Come Dancing Christmas special.
The broadcaster can't wait for her performance but admitted pigging out on fast food due to the stress of dancing for the judges and millions of viewers.
Sara, who will be performing for the panel with pro dance partner Robin Windsor, said: “I must be the only person who has done Strictly who has actually put weight on.
“I have been so stressed about my routine and Robin’s back injury that I have been hammering the Melton Mowbrays and oven chips with salad cream! I’ve been knocking back a couple of glasses of Merlot every night as well."
Speaking to The Sun newspaper, Sara revealed how she had chosen her own outfit for the BBC One festive special this year.
She explained: “My dress is feeling a bit tight but I have chosen a dress, like my wedding dress, which is a 1950s vintage style.
“I don’t want my stomach to be on show. After having three children, my days of cropped tops and cutaway dresses are long gone!”
Other stars taking part in this year's show include West End actress Elaine Paige, singer Matt Goss, EastEnders star Ricky Norwood, comic Rufus Hound and popstar Rochelle Humes.
The Strictly Come Dancing 2013 Christmas special airs at 5PM on Christmas Day (December 25).
