While she was no doubt wowing her most recent lost love while taking the stage, closer to home was her ex Ben Affleck, who also took the stage for a sketch with Jimmy Kimmel, just days after they were spotted hanging out.

Jennifer Lopez was sure to show her former fiancé Alex Rodriguez what he was missing as she stormed the stage at the Global Citizen VAX LIVE: The Concert To Reunite The World concert on Sunday

Jennifer looked breathtaking as she stormed the stage just weeks after revealing that she had split from Alex.

On the possibility of a reunion a source told in Touch: ‘[Alex] is holding out hope and that’s why he wanted to meet up with Jennifer. She agreed to see him because they do have a lot of history and they also have some business dealings together. Alex really thinks they could make it work, but in Jen’s mind, romantically it’s over.’

During her performance on Sunday, Jennifer first took to the stage to sing the iconic Neil Diamond song Sweet Caroline, joined by her mother Guadalupe, with Lopez revealing her mother used to sing that song to her.

‘Lets sing it like a lullaby, and let’s help her out,’ Lopez said to the audience, before turning to her mother and stating, ‘Sing it like you used to sing it to me,’ in the midst of a unique ‘jungle’ set.
