It's been 12 years since Cindy Margolis won the Guinness World Record for "Most Downloaded" woman ... but people still can't stop eyeing her goods -- in fact, someone plundered the model's L.A. home last week, stealing $1.4 million worth of stuff.
The burglary took place the morning of May 22nd -- and sources tell TMZ, Cindy's mother was at home sleeping while it took place.
We're told the culprit made off with jewelry, TVs, a laptop, artwork, and her son's valuable sports memorabilia, including several jerseys signed by Michael Jordan, Kobe Bryant, and Shaq.
We're told a suspect has already been arrested in connection with the burglary -- but the investigation is still ongoing.
So far, Cindy -- who stars in the upcoming reality show "Beverly Hills Nannies" -- has only recovered her laptop ... but wanted to express, "My most heartfelt gratitude to the LAPD."
