No one knows who will replace Michael Strahan on Live! with Kelly and Michael, but Kelly Ripa will have all kinds of guest co-hosts by her side in the months to come -- including BFFs Andy Cohen and Anderson Cooper!

"They'll do the same thing they did when they found Michael ... they'll rotate a bunch of people in," a source told People. "Expect to see people like Anderson Cooper, Andy Cohen, Josh Groban and Seth Meyers. They all came on a lot last time and she loved them. She is really close with Anderson and Andy and she loves them. But she's open to trying a bunch of different people. It was clear she really liked the process last time."

Strahan made the somewhat shocking announcement last week that he will be moving to Good Morning America in September, and his last day with Ripa is May 13, though she's not opposed to him leaving earlier.

"Who knows how long it will take [to find a replacement]," a source added to People. "They're prepared to keep cycling people through even if its not resolved by the fall." That seems like so far away!
