The actress and her husband joined a familiar friend in the Tennessee city.
There, they joined a familiar face for fans of Bell's hit comedy series The Good Place: cast member Kirby Howell-Baptiste, who played Simone.
It looks like Howell-Baptiste and Bell formed a strong connection while working on the fan-favorite show, as the two had a great time in Nashville.
Bell posted a handful of pictures from the trip of herself, Shepard, Howell-Baptiste, and actor and model Larry Fields, who Howell-Baptiste wrote a children's book called Little Black Boy: Oh, the Things You Will Do! with.
Howell-Baptiste and Fields are likely partners as well, as the two attend many events together, and it looks like they share a pet cat, but nothing has been publicly confirmed.
Bell captioned the update, "#bristol baby! Thank u @nascar for the fun Nashville for the style and @kirbyhowellbaptiste and @iamlarryfields for being the best travel buddies. 💜 And as always the hostess with the mostess @hays_estes."
The four watched a Nascar race at Bristol Motor Speedway, ate some good food together, and in Bell and Howell-Baptiste's case, wore matching jewelry.
They also got a photo with Nascar driver Bubba Wallace, while another picture shows Shepard lifting Bell up for a dramatic kiss.
Howell-Baptiste commented on Bell's post, "🔥SEXY🔥," about the pair's matching rings that spell out the word.
Many fans loved seeing Bell and her former co-star together again, with one person commenting, "MY BEST DUO."
In The Good Place, Simone first appears at the beginning of Season 3, when the crew is sent back to Earth in an experiment to see if they can become better people.
She dates Chidi (William Jackson Harper) for a while, showing up again later in the afterlife.
