After a trip to the Beverly Hills Hotel last night with pals Sam and Chad, Britney changed into her bright pink wig and took her new car out for a spin!

Driving around until 4am, Britney (accompanied by Sam and Chad) made a stop at Rite early this morning, where she picked up several containers of hot tea.

Bypassing all the tabloids with her picture on the cover, Brit chattered away to the paps in her British accent, telling them her new car was "just a rental," and giving the camera a dirty look when we asked if she was still seeing Adnan. Guess that answers our question!

But that wasn't the last we saw of Britney (hey, she did pick up a CASE of Red Bull)!

Just a little over an hour ago (around 7am), photogs spotted the pop princess in the Hollywood Hills, in the midst of a heated argument with Sam.

Stay tuned - we've got video of the tiff with Sam coming soon!
