Beyoncé, who announced last month at the VMAs that she was pregnant, has revealed that she is having a lot of fun with her pregnancy so far.

The 30-year-old megastar was speaking at the launch of her new fashion line for the House of Dereon, and explained how hard it was to hide from everyone:

"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!"

The 'Crazy In Love' singer, who married rapper Jay-Z in April 2008, was wearing some of her own designs on the night, although the House of Dereon doesn't have a maternity line yet:

"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!"
