Justin Timberlake is the voice of the famous "I'm Lovin' It" jingle from McDonalds!

Justin Timberlake is a triple threat. He sings, he acts, he dances. He does more than that, but those are the three main ones. He's a modern day renaissance man. It turns out he also has a penchant for writing catchy jingles.

In 2003, he recorded the song "I'm Lovin It." McDonald's used this song as the theme for their incredibly successful and catchy "I'm Lovin It" campaign. They paid him $6 million. A tour called Justified and I'm Lovin It Live was also part of the deal.
