ABC announced Strahan's departure on Tuesday afternoon, and he joked that some reports made it seem like he had died. "It is the same channel. I am not going anywhe-re," he insisted, adding that he plans on returning as a guest co-host. "I consider myself to be a part of this family."

Strahan went on to express his gratitude to those who've watched him on Live. "You still continued to give us your eyeballs, and watch this show," he said. "Thank you guys. I couldn't have asked for better fans at all. You guys have been absolutely amazing. On top of that, I have worked with an incredible staff here."

"She's just been an amazing influence on me, and this has truly changed my life to be here with her."
