It's been a rough few days for Audrina Patridge.

First, she was almost completely omitted from The Hills Season 5 trailer. That's got to hurt. Now we've learned that her L.A. home was robbed on Sunday.

"I had a really rough day today - I got home late last night and realized that my house had been robbed," the reality star blogged. "It was pretty devastating!"

"I spent most of the morning filling out police reports and going through the house room by room making lists of everything that was taken," she went on.

She is working with police to find the culprit(s) - and it looks like she's got leads.

Said Audrina Patridge on her official site "I'm going to be posting shortly surveillance footage of the intruders with pretty clear shots of their faces."

"Most of the items that were taken are replaceable, but they took off with a few very sentimental things too. Definitely not a good way to start the week."

No word on whether the dirty Justin-Bobby is a suspect in the robbery ... or whether he merely shoplifts the poontang from Audrina and skips town before committing to a relationship or engaging in any boyfriend-like tasks.
