Fox News host Bill O'Reilly might be expanding his repertoire as he tests out the acting waters on TNT's detectives-in-heels drama "Rizzoli & Isles." The Factor host will make a cameo appearance on the show alongside actress Angie Harmon. The featured clip from Entertainment Tonight shows O’Reilly on the set of the R&! preparing to act, well, like himself.

R&I star Harmon said that at first she was worried to have O'Reilly on the set for fear cast and crew members would be "mean" to the Factor host, presumably for his political views. But alas, a relieved looking Harmon said everyone was nice to O'Reilly.

In the clip, O'Reilly explains:“I’m used to just me and one pinhead guest and I’m just pounding that person, but now I’ve got to be listening to the nuance of the lines.”

Watch the clip from Entertainment Tonight and see if Bill comes off as a popinjay:
