Kelly Ripa isn't ready to have one co-host just yet, a source close to "Live! With Kelly" tells ET.

Michael Strahan left the show in May to accept a full-time co-anchor job at "Good Morning America," which he started on Tuesday, and Live! has yet to find his permanent replacement. Instead, Ripa has had numerous guest co-hosts over the summer, including Anderson Cooper, Andy Cohen, Morris Chestnut, Carrie Ann Inaba, Jimmy Kimmel and Fred Savage.

"The show is going to stick to doing a round robin shuffle of guest co-hosts for the time being," the source explains. "Kelly likes the dynamic right now, so they're not in a hurry to make a decision anymore."

The source adds that the daytime talk show may postpone naming a permanent co-host until November.

When reached for comment, a show spokesperson told ET, "Kelly has always said that she wants a partner, and that hasn't changed. There is no timeframe for the co-host announcement, so there's nothing to postpone."

On Wednesday, Ripa made a "big announcement" that she would be co-hosting an episode with one lucky viewer. "Now it's time to put your mouths where your thumbs are," she quipped, adding that she's read social media comments that call her job easy. "I'm building a co-host empire."

As for how Strahan feels about the future of "Live!," he told ET that he has put all the drama surrounding his exit behind him. When asked who he thinks should be Ripa's new co-host, he confessed, "I haven't seen it. I wouldn't be able to tell you."
