Nicole Richie was spotted leaving her El Lay gym yesterday.
She was apparently in there for TWO HOURS!
We bet she worked up one heck of a sweat because she was hiding her face from the paps on her way out.
Hmm… we think we've seen her with this look before!
C'mon, gurl! Let's see that pretty face!
You've got nothing to hide!
You're prolly one of the fittest ladies around!
Check out some more pics (below) of the lovely Nicole!
