Lindsay Lohan's Alleged Attacker -- I'm THRILLED the Charges Were Dropped

There are two things we learned from the following clip:

1) The man who allegedly attacked Lindsay Lohan in a hotel room last month is glad the charges were dropped.

2) Our photog is really, REALLY out of shape.

We spotted Christian LaBella at LAX this weekend ... and of course, our guy wanted to ask about the alleged NYC incident -- when LiLo had him arrested after telling cops he attacked her when she confronted him about secretly taking pictures and video of her in the hotel room.

(Officials eventually dropped the case after investigators determined there was not enough evidence to support LiLo's claims.)

Problem is, Christian was walking up some stairs in the parking garage ... and our guy is usually an escalator type of guy ... because he's large.

So, when our guy finally caught up to LaBella ... the question came out like this ...

"Have you talked to [Lindsay] ... (deep breath) ... since the charges were dropped ... that's the one question ... (deeper breath) ... are you guys sill friends (gasping for air)."

Fortunately, our guy eventually caught his breath ... oh, and Christian answered the question.
