London, Jan 18: Singer Rihanna sometimes works out at 2 a.m., says her fitness expert Ary Nunez.
Nunez, who has been working with the 23-year-old for four years, says Rihanna is so obsessed with maintaining her trim figure and toned shape that she has the exercise guru on call at any time of the day.
“Working with an artist like Rihanna has different demands than most. We train when she’s ready…even if we’re on the road and it’s 2 a.m. in the morning. I’m on call 24X7 with her,” femalefirst.co.uk quoted Nunez as saying.
