Miley Cyrus @ The Grove THE CLIMB

Did anyone go to this? Photo Credit: WENN. Video under! Miley is so obsessed with her cell phone that she leaves it on when she's working: 'The funniest scene was also the saddest. My character in The Last Song visits her terminally-ill dad in hospital and is struggling to hold back the tears.

It was absolutely silent on set and suddenly my mobile phone goes off playing Don't Worry Be Happy. I'm just so anxious about losing my phone I always have it with me. That was quite embarrassing, but also absolutely hilarious.'

UPDATE: Jordan Pruitt performed too. Thx Samantha!
