Cristiano Ronaldo, LeBron James, President Barack Obama, Beyonce, Jennifer Lopez, Lil Wayne & Kevin Durant: Charity Celebrity All-Star Ice Bucket Nomination Challenge In Full Flow

Superstars Cristiano Ronaldo and LeBron James are used to the limelight, and having celebrity friends, but they've truly put this to the test with the celebrity ice bucket nomination challenge. It's now in full flow after Kevin Durant nominated James and Darren Fletcher nominated Ronaldo. Now James has nominated President Barack Obama, whilst Ronaldo has nominated Beyonce, Jennifer Lopez and Lil Wayne. Is this the coolest thing celebrities have done in recent memory?

Ronaldo stripped down and took part in the challenge, pouring two buckets of cold water over himself for charity, and now he's forcing superstar women to do the same. Could this idea be any more hilarious? Money is coming in left, right and center, as are laughs. James was challenged by his good buddy Durant, and it seems like calling out the President was no big deal. At least he has met him after winning NBA championships.

How will Obama find his nomination, and more importantly, who will he nominate? This can only be a good thing, with money being raised and celebrities using their power for a good cause, showing that they're not only in it for themselves. The sensation has spread like wildfire, and the world are sitting back, enjoying it, and wondering how far this idea can go. In this day and age, it seems when the world pulls together through any means, they can achieve just about anything.

If you were a celebrity, which 3 people would you choose to nominate? Beyonce, you're next.
