Reality TV star Jonathan Cheban has learned his lesson about posting pictures of expensive items on social media.
Cheban, who now has his own reality TV show no doubt thanks to his famous friend Kim Kardashian, was enjoying a lavish lunch in Southampton when he posted a snap of his 22-carat diamond-encrusted Jacob & Co watch, reportedly worth $AU545,000, to his Instagram page.
"I think I overdressed my wrist today . . . 22 karats is a bit much for daytime LOL," he wrote with the image.
Shortly after the image appeared to his 545,000 followers, Cheban was confronted by a passer-by who began asking the reality star questions.
"A guy came over and started asking some questions,” a source told the New York Post.
“Jonathan was very friendly. But then the guy grabbed Jonathan . . . and tried to steal his half-million-dollar watch! Jonathan fought back to stop him, and he pushed Jonathan to the floor.”
A security guard is then said to have broken up the scuffle before the brazen thief took off - sans Cheban's 22-carat bling.
A friend close to Cheban told the newspaper that he wasn't hurt but decided not to inform police of the incident because he "didn't want to deal with reports".
