The hangout reportedly isn't their first this month.
Multiple sources say the couple also hung out last week, reuniting soon after Gomez's kidney transplant.
It's been quite a few years since Jelena fans witnessed their two favs together.
The couple began dating in 2011 and broke up in 2014 after a tumultuous relationship.
The two publicly dealt with their breakup and have been warding off rumors of their reconciliation ever since.
"I think we're both just on our own journeys of just figuring ourselves out and I think maybe once we figure ourselves out we can come together and make an awesome duo or you know, she'll find someone awesome; I'll find someone awesome," Bieber told Ellen DeGeneres back in 2015. "I just want her to be happy, honestly."
More recently, Bieber released a song called "Friends."
Fans couldn't help but speculate the song was about his former relationship with Gomez, as the lyrics read, "Can we still be friends? / Doesn't have to end / And if it ends, can we be friends?"
