Ben Affleck and Jennifer Lopez both attended this weekend's charity concert VAX LIVE.

Just two days before this event, the former power couple was spotted hanging out at the singer-actress Los Angeles mansion.

Now, fans are happy there was another Bennifer reunion that happened, all for good cause.

On Sunday, the "Hustlers" actress performed at the Global Citizen's VAX LIVE charity concert, which is for the benefit of accessibility of the COVID-19 vaccine globally.

Ben Affleck also made an appearance at the show, joined by his friend Jimmy Kimmel, who dressed as the Robin to Affleck's Batman.

With this news, social media users questioned whether the DC Universe actor and the "Hit On The Floor" hitmaker mingled backstage or attended the charity event together, following from JLo's public split from Alex Rodriguez in April.

Another speculation that something is going on between JLo and Affleck was because of the singer's song choice.

She invited her mom on stage as they sang Neil Diamond's song "Sweet Caroline," opting the name out for Jennifer instead of Caroline.

But according to fans, the song doesn't just hold a childhood connection to Jennifer Lopez, as it's also a song being sung during the eighth inning of every baseball game for Red Sox.

Ben Affleck is known to be a proud Boston native and is a massive supporter of the Boston Red Sox.

Now, fans have speculated if Jennifer Lopez's song was also a subtle message of support for Ben Affleck.
