Several The Bachelor fan pages on Instagram, such as Bachelor Nation Scoop, shared a photo of the trio sitting at a table together outside at a restaurant.
In the photo, Hannah can be seen sweetly smiling at Tyler on the other side of the table.
Jacob, a 27-year-old photographer, later uploaded a selfie with Hannah to his Instagram Stories and captioned it, "LA Skater girl vibes @hannahbrown," according toUs Weekly.
Bachelor Nation began speculating Hannah and Tyler might have reunited to appear on their friend Matt James' season of The Bachelor, but Matt is currently filming Season 25 in Pennsylvania rather than at the famed The Bachelor mansion in Malibu, CA.
It therefore appears Hannah and Tyler's gathering was strictly friendly.
Tyler competed on Hannah's season of The Bachelorette in 2019 and finished as the runner-up behind winner Jed Wyatt, whom Hannah dumped five weeks after getting engaged because she discovered he had a girlfriend back home in Nashville, TN, while filming the show.
Hannah and Tyler's time together gave The Bachelorette fans hope they may have reconciled and were dating again, but both individuals confirmed in subsequent months they're just friends and still single.
Tyler admitted to Us in August that he got "crushed" on The Bachelorette and so he's pushed off the idea of getting engaged in the near future and is just working on himself. However, he'd like to be married with children by age 34.
Had Hannah picked Tyler in the end on The Bachelorette, they could be engaged and planning a wedding right now.
"It's definitely something that I think about and we've talked about before. There's all these what-ifs, you know? But you can't live in that world. What-ifs will kill you. You know? So, I try to stay away from that kind of thinking," Tyler said.
"But she's an incredible person. I think there's no doubt we would've been just fine, but we kind of went our ways and are different people than we were then. So, that makes it a little different and a little more difficult."
Tyler added he's "lucky to have [Hannah] as a friend" in his life now.
As for what he's looking for in a partner, Tyler said a woman who likes adventure and is ready to just get up and go at any time. More importantly, Tyler said he notices how a woman treats others, such as the servers at a restaurant.
