The `Love on Top` singer publicly announced she and husband Jay-Z are expecting their first child together at the MTV Video Music Awards in August, and while she said it had been hard to conceal her baby bump, she is now "proud" to show it off to the world.
Speaking at the launch of her House of Dereon fashion line at London Fashion Week, Beyonce told CNN: "I am having so much fun, it has been the most fun time now that it has been announced.
"It was really difficult to conceal. But now I can be proud and excited about it, I`m having so much fun shopping - it`s great!"
Although they were not designed as maternity wear, Beyonce, 30, is still wearing lines from her new range, and they are fitting her well.
She added: "What I`m wearing today is part of the collection; it`s not supposed to be maternity wear, but it actually is really good for the maternity. We do have some things that I am still trying to rock!"
