Pop acts on talk television this week include ‘American Idol’ judges Paula Abdul, Simon Cowell, and Randy Jackson on the Tonight Show with Jay Leno tonight, while Jennifer Love Hewitt and Michelle Branch appear on Live with Regis and Kelly on Tuesday. Also on Tuesday, ‘American Idol’ Tamyra Gray will appear on the Caroline Rhea Show, and former Spice Girl Geri Halliwell is guest co-hosting on The View. On Wednesday, look for Geri again on Late Night with Conan O’Brien, while t.A.T.u. appears on Last Call with Carson Daly. On Thursday, t.A.T.u. again appears on the Late Late Show with Craig Kilborn. Finally on Friday, look for LaToya Jackson on The View. And with Christina Aguilera on SNL this weekend and being in New York, perhaps she’ll make a surprise visit to TRL this week.
