Whats the name of this song by P!NK?

ok ive been trying to think of the name of this song. i dont listen to pink, but she has a super famous song that i lost the name of. in the music video, she is like an outlaw badass in an old western town. i asked chacha like a thousand times. they kept telling me the name was "So What" but that isnt the song. its a different song. better than that one. help me!
