Britney Spears BSpearsAttack100707_2.jpg

Some sh*t went down tonight as Britney and her sister attempted to grab a coffee at Starbucks this evening around 5:30. Brit dropped off her sis to go inside and order while she looked for a parking spot and when Britney joined Jamie Lynn inside to pick up their drinks, a psycho woman yelled out:

"We don't want you here!"

Jamie Lynn responded to try and shut up the crazy lady and that's when the deranged lunatic apparently attempted to push Jamie Lynn! WFT?!

Britney and her sister made a quick escape to the sushi restaurant nearby and stayed for an hour. When they emerged, the wild woman was gone.
