George Clooney didn't just break off his fairytale romance with Sarah Larson — he did it abruptly, leaving the former cocktail waitress shocked and heartbroken and moving back to Las Vegas, friends of the former couple tell FOXNews.com.

“She thought they were getting married. Instead, she got dumped,” a friend said. “She’s really upset. Devastated.”

Larson found herself teary-eyed, packing her bags and walking out the door of the home the couple had shared in Los Angeles.

Friends said the 29-year-old fled to Las Vegas, where she was working at a nightclub in the Palms Casino Hotel before Clooney swept her off her feet one year ago.

The pretty brunette, a former "Fear Factor" reality show contestant, is already back with her old crowd. Larson made her first public appearance since the breakup on Saturday at the Palms Place Hotel & Spa’s grand opening party.

As things got serious with Clooney, Larson had moved into his Los Angeles mansion, subletting her home in Las Vegas. Tongues wagged that she might be "the one" when he took her to the Oscars this year.

Less than a month ago, the couple were in New York celebrating the actor’s 47th birthday. They were taking it slow, but they were planning to eventually wed, they told friends at the time.

“She’s totally heartbroken and doesn’t deserve this,” a friend said. “It came out of nowhere. They had made all these plans.”

Adding insult to injury, friends say, is this month’s issue of Harper's Bazaar, which features Larson posed on a motorcycle, clad in Dolce & Gabbana.

The headline reads: “It Girl: Sarah Larson. Don't hate her because she's beautiful, fearless … and dates George Clooney.”

Even more painful: In the accompanying interview, Larson gushes about the love of her life, George Clooney.

The Oscar-winning actor/director/producer is one of Hollywood’s notorious bachelors — he’s been named People magazine’s Most Eligible Bachelor and Sexiest Man Alive (twice) and has been romantically tied to a bevy of Hollywood beauties.

He’s been married once, for four years to actress Talia Balsam. Ever since their split in 1993, Clooney has sworn he’ll never remarry. He’s had relationships with actresses Krista Allen and television host Lisa Snowdon.
