Jennifer Garner recently threw herself an uncharacteristically big party for her fiftieth birthday.

The Alias alum told Town and Country Wednesday (October 26th), “I basically had a wedding for myself, I was so shocked that I was doing it.”

But it wasn’t all fun and games. The charitable actress also asked her guests to fill 5,000 backpacks each with enough food to feed a family of four for a program called Blessings in a Backpack.
