Pregnant singer Kelly Rowland is adding watch designer to her resume with a collection of timepieces for luxury brand TW Steel.

The former Destiny's Child star signed on as a company ambassador in 2012 and now she is using her fashion knowledge to create her own range for the firm.

She tells InStyle magazine, "I love the look of a masculine watch on my wrist."

She adds, "When I think about timepieces, I think class. A watch is a fine piece of jewellery on your wrist - an extra bracelet with numbers on it. And a big watch makes me feel powerful!"
