Britney Spears and her son Sean Preston leaving Johnny Rockets at the Commons at Calabasas (9/11)

Britney Spears was spotted wearing a huge diamond ring on her ring finger over the weekend, fueling speculation that she is insane and likes to act like she's engaged for the attention may be engaged. That's Britney and her son Sean Preston leaving Johnny Rockets diner on Saturday, where I'm assuming she was registering. Remember, if you do buy her a cheeseburger or a side of bacon, it's considered poor taste to bring the gift to the actual wedding. Either mail it to her or give it to her at the wedding shower. This concludes Celebslam's daily lesson on etiquette. Tomorrow -- Salad Forks: Friend or Foe?
