WEST HOLLYWOOD (TMZ) — YG claims nearly half a million dollars in bling was taken right from under his nose — and cops are on the case.

Law enforcement sources tell TMZ … the rapper filed a police report Monday in L.A. for grand theft, telling police over $400,000 in personal jewelry had recently been jacked from his hotel room at the London. And, by “recently,” we mean almost an entire week earlier.

We’re told YG claims sometime between 11 PM on NYE and 11 AM the next morning, a briefcase containing high-priced pieces that had been placed on top of a safe was a little lighter than usual. YG told cops he noticed the missing valuables on Jan. 1 … but for some reason, didn’t get around to making an official report until 5 days later.

No suspects have been identified in the case yet … we’re told YG noted he had people coming in and out of his room that night. Makes sense — it was a big holiday, after all.

That said, our sources say detectives will be looking into possible surveillance footage in and around the area to see if they can spot anything … in addition to their usual investigatory methods.

LOS ANGELES — MTV’s “Ridiculousness” star Sterling “Steelo” Brim partied his ass off only to come home to a major party foul … after thieves allegedly broke into his pad and took off with valuable collectibles.

Law enforcement sources tell TMZ … Steelo returned to his L.A. area pad around 8:30 AM after a night of partying. But, something was amiss … he noticed stuff missing.

We’re told security footage showed at least one person people going in and out of his house. A safe was stolen as were valuable collectibles and figures. All in all … he told cops around $100k worth of stuff was pilfered. LAPD is on the case and sources say it appears thieves got into his crib through a side door.

It’s unclear if the side door was unlocked or if it was jimmied open.

Our sources say cops are also in possession of the security footage and they’re reviewing it for more clues.
