This is really tugging at our heartstrings...

Disney sweet-tart Miley Cyrus sang "The Climb" to a little girl at the Concert for Hope last night at the Staples Center in LA. (Last year's concert raised more than $1.2 mil for City of Hope's cancer research.)

See, this is why I heart Miley. Always awesome to use your celebrity power for a good cause! Grab a tissue before you watch the vid though:
