Michael Strahan may have won April Fools' Day on Thursday while shocking his fans by convincing them that his famous gap-tooth had been closed.

The Good Morning America co-host appeared to be serious when he posted a video of himself visiting Dr. Lee Gause, who was pretending to close the gap tooth.

“If I go home and say I’m going to do it, it’s going to be ‘don’t do it.’ If I post, it’ll be ‘don’t do it.’ If I talk to my friends, it’ll be ‘don’t do it.’ If I tell my business partners, it’ll be ‘don’t do it.’ But I’ve got to do what I want to do for myself,” Strahan said in the Instagram video, telling the dentist he was the “only one who knows.”

Many of his followers, who were fooled by the stunt, commented on the post to express their disappointment.

"I did it," Strahan wrote on Instagram while his fans appeared to be heartbroken.
