Taylor Swift invited Sara Bareilles on stage with her Monday night while performing in front of a sold out crowd at the Staples Center in LA. Sara and Taylor sang Sara's hit "Brave". This joint venture goes along with an ongoing tradition that Taylor began at the beginning of her RED tour.

Before Taylor brought Sara on stage she told the sold out crowd,

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."

Then she introduces Sara!

When she wraps up the RED tour at the Staples Center in LA, she will have set a new record for the stadium because she will have played her 11th sold out show. The RED tour wraps up in Nashville next month then it's off to Australia in November for another round of shows.
