This whole 10 Year Challenge thing may be way better (and safer) than the Bird Box challenge but it doesn't mean I'm participating in it all. We've already rounded up some of the best ones we've seen from Kevin Hart, Nicki Minaj, Samuel L. Jackson and covered some of the late adds like Tyga and Cardi B.

There's now a new member who joined the challenge and it's none other than Jennifer Lopez whose 10 Year Challenge is an impressive one. The "Dinero" singer shared a photo from 2008 that sees her pregnant with her twins, and seemingly about to pop. Fast forward to 2018, a hot ten years later, and there's Jennifer in a two-piece yellow bikini showing off her toned abs and toned physique. "Challenge accepted," she captioned the image.  

"I am 100 per cent convinced that working out is part of what makes me so happy," Jennifer previously stated.

"Dance has always been a huge part of my life and taking the time to move my body and do something that's so good for me is key to my happiness. And I really believe that when you take care of yourself and work to stay healthy, you're better able to take care of those you love. So working out is definitely a priority for me."
