The 26-year-old star claimed to admire the 'Promise This' singer's "funky and casual" fashion sense and declared her to be the winner of a much-hyped 'style war' with fellow X Factor judge Dannii Minogue.
She explained to Bang Showbiz: "I think Cheryl's really cute and has found a way to wear elegant dresses but also look quite funky and casual too.
"I actually really like the way Dannii did a more classic look - she looked like a lady, not like an older woman who was trying to look younger. I do think she looked great but I prefer Cheryl's style."
However, the Dancing With The Stars contestant blasted Gossip Girl actress Taylor Momsen for abusing fashion in order to become "something that she's not".
"I'm really impressed with Taylor Momsen's music but I think she's trying to be something that she's not. You can't be Cindy Lou Who and wake up the next day and be Courtney Love.
"It's not a genuine transition - when you turn yourself into something you're not with your fashion, that's when I feel like you should be arrested."
