All eyes have been on Jennifer Lopez and Ben Affleck as they seemingly rekindle their romance after the singer's split from Alex Rodriguez, but now another old flame of hers is resurfacing.

On Thursday, Sean "Diddy" Combs shared a throwback photo of himself and Lopez walking hand-in-hand.

He didn't offer much in the way of context in the caption, simply writing, "#tbt."

Fans had a good laugh in the comments about the rapper's apt timing for posting the throwback photo, with many making jokes about their romance being revived.

Lopez and Combs, known then as "Puff Daddy," were two of the 1990s and early 2000s' biggest music stars, so it makes sense that their paths would cross as some point.

According to Us Weekly, the two met on the set of a music video, though it's unclear whose video it was, or for what song.

The two remained mum about their split for a time, but the "Hustlers" star opened up in 2003 about what let to their breakup.

"It was the first time I was with someone who wasn’t faithful," JLo told Vibe magazine, (via Entertainment Weekly). "I was in this relationship with Puff where I was totally crying, crazy and going nuts, it really took my whole life in a tailspin."
