Kebe tweeted that he was going to join Newcastle on a four-year deal, but followed it up with a hasty explanation of his joke.
The first tweet read: "On my way to Newcastle, having medical then sign a 4 years contract. Thank you all for your support you've been outstanding !!!!"
Reading were quick to reveal that the winger was just joking and Kebe responded with a further tweet.
The second tweet read: "Oups i thought if you're french and play football u just pop in to Newcastle and sign a contract. Not a chance of leaving. #LoveReadingFc#"
Kebe has scored 27 league goals since joining Reading in January 2008.
