She said: ''I want to recut 'Somethin' Stupid' with Bruno Mars or [country singer] Blake Shelton.'''
Kelly, 30, also revealed she is a huge fan of country music from ewhen she was growing up.
She said: ''I love to blast 90s and 80s country music, it's my favourite kind of country. Too many couples' skates to mention.''
Music is hugely important in Kelly's life and she even has her favourite songs to clean to.
She added: ''I always put on Patsy Cline or Hank Williams records when I clean the house. They clear my mind and inspire me to clean and chill.''
