Justin Bieber's on the run!

After pulling and all-nighter at his Beverly Hills condo Tuesday night and having to answer to cops who were called on noise complaints, the trouble isn't over for The Biebs ...

X17online can report exclusively that a process server was staking out Bieber's Beverly Hills building this morning, waiting to encounter Justin so she could serve him with a lawsuit filed by an alleged victim of a car accident that took place last year.

But Bieber's no stranger to process servers and lawsuits ... he had his own ideas about avoiding being served. So just what does a pop star do to avoid a run-in like this? Well, he sent his bodyguard down to the parking garage to pull out in Biebs' red Ferrari as a decoy, then Justin himself rolled out a minute later in his black Range Rover.

The ploy did catch the process server off-guard, so when she realized it was Justin driving the Rover, she threw the papers at his windshield! Does that constitute legal service? We think not...

But Bieber was relaxed about it. He and his bodyguards went to McDonald's for lunch after narrowly escaping being served.

UPDATE:
We've just learned that Bieber was being served paperwork related to a lawsuit filed by Walter Lee, the photographer Bieber struck while exiting the Laugh Factory in West Hollywood in June of 2013. Lee filed the the suit on June 25, 2014, but by then authorities had cleared him of any wrongdoing after the crash.

Lee was walking down Sunset Blvd when he was was struck by Bieber's Ferrari, and he accused the pop star of "negligently, carelessly, recklessly, wantonly and unlawfully" causing him injuries from which he may not recover.
