Why Is Brit In A Bad Mood?

We caught up with Britney yesterday at a local Starbucks and she was NOT happy! Could it be her trouble with her mom? Bad news about her album possibly being pushed back to 2008? Or just a bad day ...

X17 has received word from our source that Britney's interest in a restraining order against her own mother is to keep her mom from visiting with Sean and Jayden at Kevin's house. Maybe she's worried the two will work together, against her, as they did just before Brit's forced stint in rehab.
