She sure knows how to make an entrance!

Last night Lindsay Lohan landed at Los Angeles International Airport, and the 26-year-old starlet turned heads in a pair of leather pants ... with a denim crotch.

Lilo will be attending the Scary Movie 5 premiere tonight, and after that we're pretty sure she's headed to Indio to party it up at Coachella this weekend. While she's going to be chatting with reporters on the red carpet, we highly doubt anyone will put her on the spot as much as David Letterman did on Tuesday night...

But back to all that leather ... what on earth inspired her to pick out this boot and pant combo?
