Jennifer Lopez has inspired Mariah Carey to lose weight. The girl who she’s given the famous line too, “I don’t know her.”

A source tells Hollywoodlife.com; “Things were getting a little out of control with her weight and she really didn’t like how things were going. And she knows she has an image to uphold, a young boyfriend and, most importantly, kids that are growing up that she wants to be around for in the near and far future. So she decided to make a change for the better and for her future. She is close to 50-years-old and instead of letting it all go she sees people like J.Lo thriving at the same age. She feels that this new look is going to give her more opportunities with her career and her life and she is determined to keep the pounds off forever!”

This proves that your haters are your best motivators.
