Carson announced the good news on Instagram Saturday by sharing an adorable photo of herself hugging her new fiance Carson McAllister.
"My love of four years @carson.mcallister proposed last night & I feel like the luckiest, happiest woman in the world," Carson, who's currently paired with Carlos PenaVega on Dancing with the Stars, wrote. "It was perfect, he's perfect #engaged."
The next day, Carson posted another image of the pair smiling in each other's arms after the beachside proposal.
"Still reminiscing," the 21-year-old Utah native captioned the picture, including a shoutout to the "sneaky photographer" who captured the sweet moments.
