EXCLUSIVE: Jennifer Lopez seemed to be in a good mood as she left a gym session with Ben Affleck and did a little skip and a jump as she left the building. J.Lo, 51, who has been training five or six days a week, is clearly having a good influence on boyfriend Ben, 48, after getting him to join her for workouts. Jen, wearing a white Guess T-shirt and purple yoga pants, arrived at the gym separately to Ben who arrived minutes behind her wearing a blue t-shirt, sweatpants and a face mask. Eye witnesses described how the couple - known as Bennifer - pulled up at the gym in separate cars and concocted an elaborate plan to avoid being photographed together. An eye witness said: “They arrived in separate vehicles to avoid being seen together. “They were inside for about 45 minutes to an hour and when Jennifer left she looked in an amazing mood. “She didn’t have a face mask on and as she walked to the car did a little skip - she certainly seems to have a ‘pep in her step’ at the moment. “Ben then followed a few minutes later and they both left separately.” Reports claim the pair have worked out in the gym separately with different trainers and J.Lo has been pushing herself hard during sessions. Jen and Ben recently reunited after 17 years apart and have been pictured at her luxury home in Miami. 24 May 2021 Pictured: Jennifer Lopez; J Lo; Ben Affleck; Bennifer.
