YUCK!!!! Rapper Lil Wayne And Christina Milian Are Photo’d OUTSIDE THEIR TOUR BUS . . . And It Looks Like They AIN’T SHOWER IN DAYS!!

: Weezy and Christina have been going EVERYWHERE TOGETHER. Christina actually left her daughter behind . . . and is traveling on tour with Wayne and Drake – as his CONCUBINE.

They popped out of Lil Wayne’s tour bus yesterday in NYC to get a bite to eat . . . and they looked like they smelled like BAD BREATH and FEET.
