Stopping by for lunch at a West Hollywood hotel, Britney Spears was out and about on Thursday (December 6).
The "X Factor" judge looked cute in a cream studded sweater, blue jeans, heeled boots, and a gray fedora as she sipped her Starbucks smoothie.
On Sunday, the pop princess celebrated her 31st birthday and her celeb pals wished her well. X Factor creator Simon Cowell teasingly tweeted her, "Happy Birthday @britneyspears you look great for 40 lots of love Simon."
The older and wiser Brit fired back with, "You're a day late @SimonCowell. Clearly your senility is to blame. I forgive you :)."
