Keke Palmer will join Michael Strahan and Sara Haines as a host of the third hour of "Good Morning America." She was filling in for Haines while she was on maternity leave. ABC has changed the third hour's name from Strahan and Sara to GMA3: Strahan, Sara, and Keke. The program was previously called GMA Day. Keke shared her new gig in a heartfelt Instagram post. "And then there were three," she wrote. "I love these two. Two of the kindest people I know. I’m thrilled! See you both in the morning." Keke Palmer turned 26 on Monday and celebrated her special day at the 2019 MTV Video Music Awards in Newark, New Jersey.
