You can probably guess the names that Facebook reports were more talked about than any other in 2015.
Taylor Swift. Kanye West. Caitlyn Jenner.
But who was the most talked-about entertainer over the past 12 months? We countdown the Top 10 below and we warn you: number-one will be a surprise...
Shakira didn't release any major hits in the U.S. in 2015. But she gave birth and she's married to a famous soccer player, so she was prominently in the news.
Few music fans had even heard of The Weeknd prior to 2015. It's safe to say everyone knows who he is now.
Caitlyn Jenner certainly made the biggest change of any celebrity in 2015. She's a woman now! Good for her!
Pitbull is a man of many trades. He raps. He hosts awards shows. He produces. The guy is everywhere!
We never want to see Drake dance to "Hotline Bling" ever again. But that doesn't mean he didn't make a big impact in 2015.
Splitting from Amber Rose didn't hurt Wiz Khalifa, apparently. It kept the artist in the news, and his collaboration on "See You Again" sure helped things.
Nicky Jam is a singer and songwriter whose real name is Nick Rivera Caminero. And who blew up in 2015.
And since he became a father toward the end of the year, we're guessing Kanye will be here again in 2016.
The only surprise here is that Taylor Swift was not number-one. But a good friend of hers did take the top spot...
Yup, Ed Sheeran, people! Chalk it up to his good looks, his two smash hits and, yes, his friendship with Swift. But Sheeran was all the rage on Facebook in 2015.
