Fox and Kelly, whose real name is Colson Baker, met in 2020 as costars in Randall Emmett's crime thriller "Midnight in the Switchgrass." During an interview on "The Drew Barrymore Show," Kelly said he initially signed on to star in the film solely because he wanted to be in scenes with Fox.

In January, the pair shared on Instagram that they were engaged. Kelly proposed using a custom engagement ring that included both an emerald and a diamond to represent their individual birthstones. Additionally, as Kelly told Vogue, the bands on the ring are actually thorns, meaning that if Fox tries to take the ring off, it hurts.

"Love is pain," Kelly told Vogue.
