WATCH: Caroline Flack sings Olly Murs' 'Wrapped Up' with alternative lyrics

Olly Murs has posted a video of fellow X Factor presenter Caroline Flack singing one of his songs with alternative lyrics.

While back stage Caroline was filmed singing along to the tune of 'Wrapped Up' with her 'fish and chip' related words.

Holding a fizzy drink in one hand and the words in the other she sings,

"I do, I do love fish with mushy peas"

"Do you want it wrapped up (with) salt and vinegar, or left open to eat right now?"

Following Olly's tweet where he said he preferred Caroline's version, she responded on Twitter retweeting and saying "Taking it VERY SERIOUSLY".

Last week Caroline and Olly popped into heat towers for an interview when Olly revealed his "little secret".
