As of my last update, there haven’t been any official announcements or reports about a special concert by Jennifer Lopez dedicated to Ben Affleck. However, if such an event were to take place, it would undoubtedly generate significant interest and excitement among fans of both Lopez and Affleck.

Lopez and Affleck’s rekindled romance has been a topic of fascination in the media, so a concert dedicated to Affleck could be seen as a heartfelt gesture of love and appreciation. It’s not uncommon for artists to draw inspiration from their personal lives and relationships when creating music, so if Lopez were to perform songs inspired by her relationship with Affleck, it could make for a poignant and memorable concert experience.
