Jennifer and Casper got together after her split from husband Marc Anthony. The two met back in 2011 when Casper was one of J.Lo's backup dancers on tour, and Jennifer was still married to Marc. They dated for a while but then broke things off in June 2014, only to get back together again less than a year later in May 2015.
Since the split, Jennifer was pictured smiling while out and about in New York City. On the other hand, Casper was photographed across town in hoodie trying to pass by under the radar.
