Pop sensation Rihanna has admitted that in order to combat the factors that attack her immune system while travelling extensively she has been actively 'nursing' herself through the '777' dates.

The Bajan beauty launched an ambitious tour and has flown on a private 777 Boeing jet from Mexico City, to Los Angeles, Toronto, Stockholm, Paris, Berlin, London and finally, New York (November 20) in support of her forthcoming new album, but explained in a behind-the-scenes video that it has been far from glamourous:

"I woke up coughing on the plane and I took some cough syrup, some cold and sinus tablets, lozenges ... I'm drinking lots of water and [multivitamin supplement] Berocca. This entire trip, in order to make it to the end, you have to literally nurse yourself every step of the way the entire time."

"Because it's so much work - so much on your body and so much on your immune system it weakens you. And you're open to so many other viruses that are just there."

Rihanna added that the guests travelling with her, which include journalists, fans and photographers, also had to keep an eye on their health:

"There's so many people on the plane. One flight alone is bad enough, seven of them... We'll definitely be sharing some flu's on this plane. I know that sounds gross but that's life. So everybody just has to make sure that they pay attention to themselves and their health throughout."
