Who will replace Regis Philbin as Kelly Ripa's co-host on "Live! With Kelly?" ABC is asking viewers to tune in Sept. 4 for the answer.

Ever since Philbin, 80, departed the talk show last year, a number of guest co-hosts have shared duties with Ripa.

ABC isn't letting on as to who will be Ripa's co-host, instead instructing viewers to find out the replacement on the talk show Sept. 4, Us Weekly reported.

Since Philbin left the show, "Live! With Kelly" has had 20 guest co-hosts.

If one were to read the tea leaves, those with the most guest co-host appearances on the show include actor Jerry O'Connell [nine,] "Saturday Night Live" head writer Seth Meyers [11,] singer Josh Groban [12,] and former NFL defensive end Michael Strahan [15.]

Meyers all but excluded himself from being in the running for Ripa's co-host.

"No, no, no, no, no," Meyers told the Orlando Sentinel when asked about whether he wants to be in contention for the gig. "I know [Philbin's replacement] is a very important thing down there. But, right now, what I would say to you: I'm really in love with the job I have. I'm very excited to be going back [to "Saturday Night Live"] for the election season, which is always fun."

Ripa's husband, actor Mark Consuelos, was also one of the guest co-hosts who appeared on "Live! With Kelly" multiple times.

But Ripa said co-hosting with her husband would be taxing on their lives.

"No one would make me happier than Mark, but he values our marriage and he says that he doesn't see how we could stay married and both do that show," Ripa told Vanity Fair in May.

If the selection were up to Ripa, she would choose CNN's Anderson Cooper, who had been a prior co-host on "Live! With Kelly."

She told Vanity Fair, "if it could be anyone in the universe, it would be Anderson Cooper."

But Cooper just started his own talk show in addition to hosting "Anderson Cooper 360" on CNN. He's also a contributor for "60 Minutes" on CBS.
