Britney Spears is known for a lot of things: her killer pop tunes, her charismatic choreography, being the best mom around... the list goes on and on.

In the post, she begged for action from you, the fan: She links to Americans for Responsible Solutions, and asks readers to "Tell the Senate: Vote to close loopholes in our gun laws."
