The hip-hop mogul is to perform his latest single `Coming Home` with his group Diddy-Dirty Money on the TV talent search show next month and will also style the aspiring singers through his Sean John clothing collection. He said: "I`m helping the contestants with their styles. I`m helping to dress them with Sean John. "I`m bringing a celebrity stylist to help us this week. We`re going try to get them to have that superstar shine and swagger that I try to exude on a daily basis. "I`m going to hit `em with some musical tips, some inspiration, some motivation, and then I`m gonna show `em how to do it. I`m going to hit that stage after I show `em how to have that swagger." This season has seen both Aerosmith rocker Steven Tyler and Jennifer Lopez - who Diddy dated for almost three years until 2001 - join the judging panel in place of Simon Cowell and Ellen DeGeneres and the rapper is impressed with how well his former lover is doing on the show. He told `Access Hollywood`: "First of all she`s just looking so good. You`ve got to give it to her for having twins and to be doing it how she`s doing it. I`m so proud of her. "The way Jennifer handled coming in after Simon, and even myself from `Making the Band,` and the way we were hard coaches - she`s been a compassionate person. She has made me cry, like, twice, and she`s looked good doing it. And she has made sense so, you know, I`m proud of her. "She`s a nice person, so when you`re super nice, your emotions get the best of you. It`s good though - it`s good to see that change in the competitive shows. I think she`s very refreshing." Catch Diddy in all of his "swagger" glory when he appears on "American Idol" on April 18 on FOX.
