Jennifer Lopez and Casper Smart are splitting after only two and a half years together

 Jennifer Lopez is a single lady once again.The 44-year-old singer-actress-dancer has split with her boyfriend of two and a half years, Casper Smart, The Huffington Post confirms. TMZ was the first to report the breakup news.According to TMZ, Lopez and her much-younger beau Smart, 27, called it quits two months ago, but kept it quiet. It was reportedly a "civil" breakup and they are still "friendly."

"It has actually been an amicable process that started a few months ago," a source close to J.Lo told Us Weekly. "It wasn't an easy decision, but they decided to stay friends ...Their relationship couldn't work with the distance. He started trying to establish his own life and career, and she is so focused on hers, and they just couldn't be all about each other anymore."

Lopez and back-up dancer Smart were first linked in the fall of 2011 following her split with ex-husband, Marc Anthony, who is the father of her 6-year-old twins, Max and Emme. Smart has been a permanent fixture in J.Lo's life since her divorce and has traveled all over the world with her on tour and for red carpet events.

"For me, it's about having a great partner to walk this life with. I have my own high standards for what I want in a partner and how I want to be treated. I bring a lot to the table," Lopez told Cosmopolitan last September. "I'm not talking about material things but what I have to offer as a person -- love and loyalty and all the things that make a good relationship."
