Smoke coming from passenger headlight

Last night i was on my way to pick up my friend and i got out and walked around the front of the car and i noticed smoke coming from behind the passenger side headlight. So i leaned in and smelled it, It smelled like burning oil or something. What do you guys think it is?

Open the hood and check the valve covers and see if they are leaking on to the exhaust. Oil smoke can come from anywhere and it just happens that it came out the passenger side of the vehicle. Of course a leak could be anywhere so you may want to investigate further.
