Telly presenter Caroline Flack is already quite petite, but the 31-year-old beauty has said she's on a diet to look good next to new X Factor judges Tulisa Contostavlos and Kelly Rowland. Speaking to Grazia, Caroline said Kelly had the "tiniest waist she'd ever seen.
Caroline takes over as host on The Xtra Factor this year from Konnie Huq, hosting the ITV2 spin-off show alongside former X Factor winner Olly Murs.
Speaking about the pressure she is under taking part in the hit TV series, Caroline says: "Kelly has the tiniest waist I've seen.
"And Tulisa's gorgeous. I'm a bit envious."
She added: "I'm on a diet. I do yoga and I try to work out."
The former host of I'm A Celebrity Get Me Out Of Here Now! confessed she felt under pressure "to be thin on TV".
“Before you do a show they want to know what you’re wearing," Caroline explained. “Viewers are watching and commenting on how you look. I couldn’t look that way naturally any more. My body’s different these days.”
The Xtra Factor returns to ITV2 later this month.
