Valentine's Day! Mayor Bloomberg's birthday! Presidents' Day! With so many wonderful occasions in the month of February, it's no surprise celebrities took to the town this week. Shia LaBeouf took his lovely girlfriend out to dinner on Valentine's Day, but the best part wasn't his burly beard. No, the actor is apparently a wonderful tipper! Plus, Kris Humphries suffered through his first post-super-short-marriage Valentine's Day (if he can make it, we all can, right?). Also, our mayor turned 70 and celebrated by eating a bunch of salt. All of this, and more celebrity sightings, straight ahead.
