Superstar singer Usher is one of the biggest stars on the music scene today. But is his recent hit song "OMG" a ripoff of a cartoon from The Simpsons?

In an episode of The Simpsons that aired 7 years ago, Homer Simpson sings a Christmas song that goes: "Christmas in December - wow, wow, wow! Give me lots of presents - now, now, now!"

Now the internet is burning up with claims that Usher's song sounds just like Homer's. The controversy is getting loads of attention and a side-by-side comparison on Youtube has gotten nearly one million hits!
