Lisa Rinna (Billie), who just made her DAYS comeback, appeared on Bravo's WATCH WHAT HAPPENS LIVE on March 6. During the game "Plead The Fifth", where celebs are put on the spot to answer three tough questions, she was asked who was the worst actor in the history of DAYS OF OUR LIVES. She thought about it and asked for help, then host Andy Cohen offered up "Stefano DiMera" and Rinna nodded her head and said, "I'm gonna go there," adding that she loves Joe Mascolo (Stefano) very much. (See the video here.) The next day, Rinna took to Twitter to apologize to her co-star: "I must apologize for my Joe Mascolo comments on wwhl. He is a Great actor and I should never had said him- when answering- I was stupid." Digest contacted Mascolo about the incident and he says, "Lisa saying that Taylor should have her lips reduced and calling me the worst actor on DAYS is sort of like the pot calling the kettles black! Watch out, Lisa. Stefano always gets revenge!"
