Impersonator Rory Bremner has a new obsession – imitating X Factor star Louis Walsh. Rory told me at Savile Row’s Winter Style Evening this week: “Louis is a great person to do. I love doing him. It’s a lot about breathing. In fact all the X Factor judges are great to do. I do Simon too – and I loved the fact Debra Stephenson has returned to her roots and is doing impressions again. He’s very talented and did well getting Cheryl Cole nailed before other people. I spoke to Ronni Ancona about it and we both think she’s done a great job.” I couldn’t agree more!
