Paris Hilton -- Repeat Swatting Victim ... That's NOT Hot

Hi, my name is Paris and I'm a two-time victim of ... SWATTING.

Welcome Paris.

TMZ has learned Paris Hilton re-joined the celeb swatting club when someone called 911 pretending to be her, and told cops she was trapped in her bedroom with a gun to her head.

Multiple police cars rushed to Paris' L.A. mansion to search for intruders after the call came in last weekend -- but all they found were Paris' pooches chillin' by themselves.

This is deja vu all over again for Paris ... TMZ broke the story when cops responded to her house 2 months ago for a very similar call.

Sources tell us, Paris wasn't home for the latest incident, and was completely unaware until she got back and saw the LAPD cruisers lined up outside her house.

As we previously reported ... Justin Timberlake, Khloe Kardashian, Selena Gomez, Russell Brand, Ryan Seacrest, Miley Cyrus and Magic Johnson have all been swatted too.
