Are Britney And Sam Fighting?

I know, I know, Britney goes to the Four Seasons hotel in Beverly Hills all the time, so what's the big deal? Well, she doesn't usually spend the night there with both dogs in tow and a pile of luggage.

We caught Britney unloading at her hotel of choice last night around 6 pm ...

Is Britney moving out of her house temporarily, after Sam just recently seemed to move in?

OR ...

Is Brit Brit on a layover on her way out of town for her birthday tomorrow? We'll keep you updated ...
