J.Lo performs at Vax concert as Ben Affleck watches...

In a show of normality, Jennifer Lopez performed onstage last night during Global Citizen Vax Live: The Concert To Reunite The World at SoFi Stadium in Inglewood, California. 

The performance will broadcast on May 8th.

Jen wore a number of dazzling outfits at the Selena Gomez-hosted event, even bringing out her mom onstage to perform with her.

Alleged hook-up partner Ben Affleck watched backstage, and of course the pair made sure not to be snapped together.

But if J.Lo had her way, a carefully staged photo op would have been the ultimate PR wet dream.
