Clad in a figure-revealing Donna Karan dress, Hollywood beauty Halle Berry proudly shows off her pregnant belly in the February issue of InStyle and gushes: “I want to stay pregnant forever!”

Asked how she is feeling, the expectant actress says: “Fantastic! Right now I have so much joy and energy. I can just go and go and go.”

She also thinks she looks more beautiful than ever. “My skin is aglow from all the hormones,” she says proudly. “I actually wear less make-up now, which is really good.”

Halle also says she wants the birth to be spectacular as it may be her only pregnancy. “I may only do this one time, so I want the moment to be as big as it can be. I want the biggest bang I can imagine.”

She says the baby will have boyfriend Gabriel Aubry’s surname - but they will not come up with a first name until the child is born. “People are always saying, ‘You mean you haven’t picked out a name yet? But I don’t know how you name a baby until you meet it,” she said.
