Beyonce Knowles is producing a range of maternity clothes.

The 'Countdown' hitmaker - who is five months pregnant with husband Jay-Z - plans to make a collection of outfits for pregnant women as part of her House of Dereon range with her mother Tina Knowles.

She said: "All I see now are clothes that are flattering on a pregnant woman. It's been so exciting for me! I love figuring out designs that make me feel edgy and sexy while pregnant."

However, the 30-year-old beauty admits she does not go out shopping too much and prefers to do all of her purchasing on the internet.

She added to Harper's Bazaar magazine: "I spent too much money shopping on the internet."

Beyonce - who also has two of her own perfumes out - recently confessed she is having trouble with her husband's fragrances since becoming pregnant, but still loved her second scent, Pulse.

She said: "Oh I smell things differently! My nose is like, 'doot, doot, doot'! I smell everything! It enhances it. If it smells bad, I smell it! My husband's fragrance, his one that I always love, I hate right now. So, thank God I love this one."
