Amid rumors that he might be replacing Michael Strahan on Live!, Anderson Cooper sat in as Kelly Ripa's guest co-host on Wednesday morning.
The friends were quite comfortable with one another as they bantered back and forth at the start of the show. The CNN journalist shared that prior to co-hosting with Ripa, he first hosted her and her family at his Connecticut home over the weekend.

"You're a gracious host," Ripa told Cooper.
The two further showcased their chemistry by attempting the samba, prior to interviewing "Rhythm is Gonna Get You" singer, Gloria Estefan. "We just made a baby," Ripa quipped after Cooper pulled her in close for the dance move.
It was a pretty active show. The pair later did a conga line with Estefan, and also attempted an acrobatic workout routine.
Prior to Strahan's departure from Live! last month, a source close to the ABC program told ET that Cooper was a frontrunner to take over for the former NFL pro. "It's likely Kelly will bring up Anderson's name as a replacement," the source said.

Cooper did address the rumors that he'll take the job while on Watch What Happens Live! last month. "Listen, I love Kelly and I think Kelly is the heart and soul of that show, and it's gonna go on and continue to be great," he told Andy Cohen. "I'm very happy at CNN. It would be a dream to work with Kelly, but nobody's offering anything."
Meanwhile, Strahan is back to work at Good Morning America, but will not take a full-time position at the morning show until September.
