Last night the Staples Center in L.A was at fever pitch with concert goers going bonkers over Taylor Swift inviting Sara Bareilles on stage to sing her latest single, Brave.

Turns out that Taylor Swift not only invited Sara Bareilles, but Cher Lloyd as well, so to say the least, the Staples Center was the place to be last night!

Before announcing Sara on stage Taylor opened up by saying: "Guys, there's a song that came out a few months ago, and I listen to it every single time I have a bad self-esteem day -- which is a lot," Swift said while introducing Bareilles. "This song is so beautifully written. It's so original. It's something I've listened to hundreds and hundreds of times by an artist who I absolutely adore. A singer-songwriter who's so incredibly talented, it's ridiculous. She came here out of the goodness of her heart to sing for you tonight."
