Britney Spears had on a sour puss yesterday (June 1) while taking her boys Jaden James and Sean Preston Federline to the amusement park at the Santa Monica Pier. Her boyfriend and ex-manager, Jason Trawick, tried to put a gentle hand on her arm, but it looks like Brit couldn’t get out of her funk.

The New York Post reported that the other night the singer started an argument with her man in a restaurant at the Mondrian hotel. “Britney was rude to the waitress and then started arguing with Jason,” shared a source. “Over 30 minutes into the meal, Britney decided she wanted to leave. She headed out of a back door of the hotel, with Jason following, still trying to calm her down.” Eww, I hate when people are rude to waitresses and waiters. So low class, like visible tracks on a weave, you could say.

This is not the first witnessed report of a bad fight between the two. Back in April Britney had a berserk moment and supposedly hit Jason. It would be nice if she didn’t have psychological issues, but newsflash, the girl has mood swings. I’m just glad she found someone like Jason who seems to care enough about her to deal with it.
