Hollywood Queen Lupita Nyong'o looked amazing at the Oscar's last weekend. So good, that apparently her dress was a target for some thieves to try and steal her dress. A successful attempt. 

According to TMZ reports:

Lupita Nyong’o’s now-famous Oscar dress — adorned in pearls — was stolen right out of her hotel room … TMZ has learned.

Law enforcement sources tell TMZ … the dress was taken out of Lupita’s room at The London West Hollywood. The dress is made of pearls … 6,000 white Akoya pearls. It’s valued at $150,000.

Our sources say Lupita told cops it was taken from her room sometime between 8 AM and 9 PM Tuesday … while she was gone.

We’re told there is security footage that cops are looking at that could catch the culprit right in the act.
