(Cover) - EN Showbiz - Beyonc Knowles has revealed that swimming in the ocean is her favourite way to relax.

The notoriously hard-working singer is famed for her perfectly groomed look. Away from red-carpet events and performing live, the singing sensation says she loves nothing more than to unwind by going on vacation and taking advantage of the open water.

The 29-year-old says this relaxation method keeps her feeling and looking good.

My favourite way to relax is to go on vacation and swim in the ocean. My skin looks healthier when I have had a break from work, she told the British edition of Glamour magazine.

The American R&B star is famed for her gorgeous curves, which are the envy of women across the globe. She puts her toned physique down to rigorous gym training and high-intensity dancing routines whilst on tour.

When I am on tour, I dance for two hours a night, and when Im not on the road, I work out a few times a week which keeps my skin glowing. I run about two miles on the treadmill and I have a great trainer. (C) Cover Media
