Jennifer Lopez's children are the "lights of her life". The 'On The Floor' hitmaker has paid tribute to her two kids, twins Max and Emme, who she has with ex-husband Marc Anthony, as they turned eight yesterday (22.02.16). Taking to Instagram to share a sweet picture of the pair, she wrote: "HAPPY BIRTHDAY TO THE LIGHTS OF MY LIFE. You have brought me nothing but joy and happiness since the very second you were born. "I am so proud of who you are and the beautiful loving caring people you are growing into. #coconuts8thBirthday. #Iloveyoubeyondforever #maxandemme #February22nd And Thank you everyone for all the beautiful birthday wishes and videos. They are so precious!! (sic)" Meanwhile, the 46-year-old actress previously admitted it is a bit of a "juggling act" trying to balance her work and family commitments. She shared: "I take it step by step and day by day and everyone in my life knows the commitments I have - it was super overwhelming! "Before getting to the American Music Awards in November last year, and after we created the show, and after we filmed 'Shades of Blue', and then filming Idol on the weekends ... I was like, 'Maybe this is the first time I bit off more than I could chew.' But you know what, I take it day by day and I have an incredible support system."
