Regis Philbin isn't ready to say who he thinks would be the best replacement for him when he leaves 'Live' at the end of the summer, but one of the names that keeps popping up in the executive suites over at ABC is none other than Lisa Rinna.

"Lisa has proved she can do the job," one exec tells me. "She has co-hosted the show with Regis, filled in for Joy Behar on her show and was even better than Billy Bush when she stepped into his shoes on 'Access Hollywood's' new daytime show."
