Ray J is making a dire plea to his fans. According to the singer, someone stole his heart monitor off his chest during a recent concert. The singer tells TMZ that while performing “One Wish,” he often jumps into the crowd to “touch the people.” However, this time things didn’t go as planned. “If you have the heart monitor, just let us know how we can get it back,” Ray J pleads. Ray J says if necessary, he’ll get the monitor replaced. However, he has been without the monitor for nearly two weeks and cannot access the important data he needs. “It’s important, I need it for analytics.”
