It is unclear at this time whether J.Lo, Leah, 46, and Casper were all attending a star-studded event or if the run-in was just a coincidence. Jennifer and Casper previously started dating in October 2011. They split in June 2014, but reconciled in January 2015. They called it quits again in August 2016.

Marc "has never stopped loving her," an insider recently revealed to Life & Style. "He wants her back."
