Nicole Scherzinger looked dazzling at the X- Factor Newcaslte auditions on her first day as a full-time judge. The former Pussycat Dolls singer, 33, who was a guest judge on the show in 2010, was confirmed as Kelly Rowland\'s replacement last week. Stood outside the Metro Radio Arena, Nicole posed for photographs, wearing a one shoulder, emerald green dress that looked gorgeous on her. She teamed the ensemble with a pair of towering silver peep toe heels and a matching metallic belt. Scherzinger has told reporters that she\'s excited to be re-joining the show; this time on a more permanent basis. \"It\'s where I got my start, so it feels great to come full circle. I can\'t wait to see what talent the UK has to offer and to help inspire and bring out the best in these artists.”
