Sandra Bullock dropped her son Louis off at school in Los Angeles, CA on Friday.

Clad in an all black workout ensemble, the "Miss Congeniality" actress kept her head low while making her way past the nearby shutterbugs.

In other news, Sandra will soon be getting busy with filming for the "Despicable Me" spinoff titled, "Minions," in which it was recently announced she will be starring alongside "Mad Men" star Jon Hamm.

The animated flick, which Bullock and Hamm will play a married couple, will follow the lives of the unpredictably hilarious Minions who became instantly popular in the original 2010 film.
