"BIG BROTHER TATUM," Tia and Taylor, 32, captioned the video.

During her first Bachelor in Paradise appearance, Tia was memorably dumped by Colton Underwood, who subsequently when on to become The Bachelor's Season 23 star. (Three years later, Colton also publicly came out as gay.)

Tia sparked romances with Kenny Braasch, James Bonsall, Blake Monar, and Aaron Clancy during her second Bachelor in Paradise stint in 2021, but she chose to leave Mexico on her own towards the end of the process.

Tia seemed most interested in Blake, but he didn't put enough effort into their relationship, according to the bachelorette.

Tia revealed on Bachelor in Paradise that she had a history of dating men "who don't care" enough to woo her, and she's a person who believes actions speak louder than words.
