Rihanna has apologized to the 150 fans and journalists on her disastrous 777 tour.

The "Diamonds" hitmaker - who has been relying on a mixture of cough syrup and lozenges to keep her going during the whirlwind promotional trip for her new album Unapologetic that ends in New York tonight after which she will have done seven concerts in seven cities in seven days - has admitted she struggled during the tour and it was impossible to spend time with everyone but insisted she has no regrets.

Media members on the tour have been complaining all week about the poor conditions including a lack of food, sleep and extremely limited access to the singer for interviews. An Australian journalist streaked through the plane in protest, while others made up songs about the poor conditions.

According to USMagazine.com, the 24-year-old addressed the crowd at the back of their private plane this morning saying, "Guess what, we made it! This has been an experience that I will never ever forget. I barely slept. My sleeping was all done on this plane, I want to thank everyone for making this trip the sh**. I want to see the naked Australian! I was glad I did this, absolutely. Tonight is the night everything we did this week goes off. I know you guys got barely any dirt. But I had to be good. I still sound like sh**. It's impossible to spend time with everybody, and I'm sorry I didn't. But this was excellent and I would definitely do it again."
