Brit: White Mercedes, Orange Soda, Pink Eye

Britney Spears spent the night with J.R. Rotem -- pink eye alert!

TMZ caught Brit, her travelin' pup, London, and J.R. -- driving all around L.A. last night. Rotem took the wheel as they banged U-turns all over the place. Their destination was unknown, and even Britney didn't have a clue where the heck they were going.

While frenetically cruisin' the Pacific Coast Highway, they stopped at Brit's favorite hangout -- a gas station -- to pick up some Sunkist orange soda. They ended up getting back to Brit's Malibu pad around 2:30 AM.
