This is something we can all definitely agree on. There's no doubt that Jennifer Lopez is one of the hardest working celebrities in the business, as she somehow manages to juggle her multiple projects, concerts, television shows and music career while still raising her twin children at home.

And how does she do it all? Well, according to her boyfriend Casper Smart, she's simply "not human."

"She's worked really, really hard on this show, even when she was in New York with Shades—which is by the way a No. 1 show—and American Idol, and press, and she's flying all around bouncing everywhere. And she still makes the time to do this ... It was so her month. It's crazy. Between Shades and Idol and this, it's bananas," Smart said, according to NaughtyGossip on Monday. "She's not human. She's like supernatural Wonder Woman. She's not from this planet."

What's more, Lopez even managed to make the time to perform at a Russian' billionaire's wedding this past week. Her motive? $5 million for the performance.

One source dished, "She has always been about the money. People in her team have begged her not to make terrible movies but if the money was big enough, she would make them. The same is true about performing. She will not get out of bed for less than $1 million. But if you will pay her lots and lots of money, she will show up. She really doesn't care what even it is as long as the money is right."

The insider added, "She is a business woman. Be honest, do you think she is a judge on AMERICAN IDOL because it is great TV or that it helps her career?—She is doing it for the CASH, CASH, CASH."
