Say cheese! Today, the White House released the first official family photo of the Obamas.

Shot Sept. 1 by famed photographer Annie Leibovitz, the First Family -- President Barack Obama, First Lady Michelle Obama and daughters Malia Ann and Natasha (Sasha) Obama -- smiles from within the White House's Green Room.

Noticeably absent? Bo, their Portugese water dog.

The photo is available for download on The Official White House Photostream.
