Justin Timberlake – McDonald’s, Estimated $6 Million

There isn’t a person on this planet who doesn’t know McDonald’s “I’m Lovin It” slogan. However, not many remember that it was originally recorded by Justin Timberlake in 2003. Timberlake had no idea the song would become so popular and will stay with the brand even today, or he would’ve asked for more than the amount he was paid.

Timberlake mentioned he regrets taking on the endorsement deal with McDonald’s but never really explained why. Well, our guess is that he probably expected extra royalties after the success of the song. We feel you, Justin!
