Singer Sara Bareilles has appealed to her celebrity friends to lend her a tour bus after the coach she was travelling in broke down.

The Brave star is currently on the road in the U.S. but hit a major setback on Thursday morning (17Jul14) when her tour bus broke down just hours before her planned show in Philadelphia, Pennsylvania.

Bareilles began tweeting from the side of the road, writing, "Hey artist friends: I'm in need of a tour bus. Sadly, not joking. If you're fancy and own one you want rented by a lady like me, let me know?"

She then added a video to show she is serious, filming the broken down bus and her crew as they unloaded equipment from it, adding, "Hey, no really, we're on the side of the road. There's traffic... so if you know anybody - help a sister out!"
