The 'Talk That Talk' singer has posted pictures of herself exercising and posing while on vacation in Hawaii.

Rihanna has updated fans on her Hawaiian holiday by posting a series of pictures showing the singer relaxing with friends and working out.

The 'We Found Love' singer posted the pictures today (19th January) after spending the past week in Hawaii taking a break following her 98-date 'Loud' world tour.

Among the new photos tweeted by Rihanna this morning is a shot of herself running on a cross trainer wearing only a white bikini and dark shades, as well one of her posing on a surf board along with several friends.

Earlier today Rihanna confirmed she will perform her Coldplay collaboration 'Princess Of China' with the indie band at next month's Grammy Awards 2011.

The 'You Da One' singer also starred in a brand new advertising campaign for her Armani underwear and jeans line earlier this week.
