Post Malone‘s heart is no longer taken by his fiancée, because TMZ has learned they’re officially done … and he’s moved on with a new lady by his side!

We’re told Posty and his ex separated toward the end of 2024 … and he and his new boo, Christy Lee, have been seeing each other since at least the beginning of this year.

In a recent TikTok video, Christy and Post were all about the PDA — they couldn’t have looked more smitten, as Christy’s hand was tightly wrapped around Post’s arm on the upper level of a bar, while he spotted a fan down below and gave a friendly wave.

The couple was spotted strolling in Rome in January, going out to dinner at the famed Mascagni Hotel.

Not a whole lot is known about Christy, but a quick peek at her LinkedIn reveals she’s a Parsons School of Design student based in NYC.

She also scored an internship with celebrity stylist Kristina Askerova last year — so she’s got a strong creative background, working with celebs like Bella Thorne, Brooks Nader, and Charlotte McKinney.
