Miley Cyrus and Taylor Swift at 51st Annual Grammy Award

Girl power Miley Cyrus and Taylor Swift are performing together with Swift’s song “15″ at Sunday’s Grammy Award.

Swift said, the lyrics are very inspiring. The song is all about “all you think you know at 15 and all things that you learn.”

A lot of girls are inspired by them, so the song is them giving their own advice.

This song shows how the only things you’re left with is your best friend and a learning experience.

The two have been BFFs for a long time, so it wasn’t tough to get them to agree to a duet.

The 51st Annual Grammy Awards will air live from the Staples Center in L.A. Sunday at 8 p.m. on CBS.

Another hot topic for the girls was how Cyrus recently traded in her Porsche for a more environmentally friendly Prius. She said that, “The Porsche is really hard to drive, I thought I could drive that thing. I got in it and was like, ‘Hold the phone, this thing is huge!’ ” ha ha ha… she got scared by the size.
