Britney needs to lay off the hooch, y'all.

Britney Stumbles -- Almost Drops Baby Sean

Britney Spears stumbled this afternoon as she was leaving a New York City hotel and almost dropped little Sean Preston.

We're told Britney was holding a drink in her left hand and Sean in her right as she maneuvered through a crowd of onlookers. Britney moves through the crowd and then she suddenly trips, the baby's head goes backward and his hat flies off his head. Britney regained her balance and the baby seemed ok.
