Marc Anthony and Jennifer Lopez's split might have come as a surprise, but a source close to the couple told People magazine that it was the result of "months of nonstop arguing."

"Marc and Jennifer decided it's best to go their separate ways for the sake of their two kids," the source told the weekly. "[Jennifer] is, of course, sad that she and Marc didn't work out, but they both feel they have tried everything."

Marc Anthony briefly touched on his recent split from Jennifer Lopez during a concert in Colombia on Saturday night.

According to a report by People magazine, the singer was heard joking about his break-up. "They're saying I'm single," the 42-year-old said on stage, according to the magazine. The singer was also spotted "playfully flirting" with women in the crowd.
