It's week two of Celebrity Operation Transformation as the five celebrity leaders settle into their new healthier lifestyles and dive into training for their toughest fitness challenge yet. Looking to get into shape are X Factor singer Mary Byrne, beauty expert Triona McCarthy, chef Gary O'Hanlon, social media influencer James Patrice and singer and (former contestant on The Voice) Kayleigh Cullinan. Question is though, will Triona be giving up the spanks for her weigh-in this time round? (That was an issue last week, we're not being weird, swear).
