Will they get this notification?

I was looking at my activity page on my twitter app for iphone and someone I follow favorited a tweet of someone they follow and I accidentally clicked to follow that person but I immediately unfollowed. Will that person get a notification that I followed them? And will it still show up on the activity page?

Added (1). It wasn't a celeb. It was a regular person.

Who is he who is he? You love him you love him. Blah blah blah blah quite and he is kissing in the tree.

Ya if he checks his male frequently he will know.

No
