The two stars have been flaunting their love all over Hollywood, but finally took a big step when they hit a red carpet together for the first time.
It went down Wednesday night at the Nights of the Jack Friends and Family Night 2019 held at King Gillette Ranch in Calabasas.
Posing for the cameras, "The Hills" star and the model poured on the PDA, and even smooched for the cameras.
Brody looked a bit awkward at first, but eventually loosened up and appeared to be enjoying himself.
The two have had a whirlwind romance and just recently returned from a trip out to the mountains in Montana.
During the vacay, which included horseback riding, hunting and fishing, Brody and Josie both declared their relationship, "Instagram Official," with dueling posts on social media.
"I’d rather be lost in the woods than found in the city," the son of Caitlyn Jenner wrote on his photo with Josie. She responded with her own photo, and simply wrote, "Thank you" in the caption.
Even Brody's "The Hills" co-stars noticed the significance, with Brandon Lee telling Brody, "Woah she made the main page... this is serious."
Nights of the Jack is a pretty cool experience as guests trek around a half-mile trail on King Gillette Ranch and check out tons of amazing pumpkin carvings that are fully lit up.
This year the festival has teamed up with Nickelodeon to feature a special "Are You Afraid of the Dark?" tent and even an impressive pumpkin display that pays tribute to "Spongebob Squarepants."
