While some "celebrities" like Kourtney Kardashian whore their unborn children out for headlines, others choose to keep their private lives to themselves.

Gisele Bundchen is one of those people. The supermodel and Tom Brady aren't ones to divulge pregnancy details - or even find them out personally!

Rumors may be flying that she’s expecting a baby boy, but pregnant Gisele Bundchen says she doesn’t yet know the sex of her baby. Nor will she!

"We decided not to know,” Bündchen, who is expecting her first child, tells Brazilian magazine Caras. "We will only know when it is born, in December."

"I want the emotion of finding out then if it is a boy or a girl," she added.

Not finding out the sex of the baby doesn't mean she’s not already scouting baby clothes - and shoes. Bundchen, who markets a line of sandals in Brazil, loves the baby-size ones: “The baby versions are really cute," she says.

And while she’s already six months pregnant - time flies when you deny it repeatedly, then don't publicize it - Gisele has hardly been slowing down.

She's been busy as the new goodwill ambassador for the United Nations Environmental Program, and is getting her pilot’s license next month.

"I am going to keep traveling, but my home is in Boston," says Bundchen, who moved there from New York City to be close to her husband, who plays quarterback for the New England Patriots (maybe you've heard of him).

Whether they're having a boy or girl, these things remain clear:

• It's going to be one beautiful, adorable celebrity baby.
• Tom Brady has seen Gisele nude at least once. Jerk.

Here's a Bones spoiler for you: David Boreanaz's new bundle of joy is here!

The actor's wife, Jaime Bergman, delivered the couple's second child, daughter Bardot Vita Boreanaz, on Monday. Bardot joins big brother Jaden Rayne, 7.

The birth comes as a relief to David Boreanaz, who had been staying close to home in case Jamie Bergman, who had been on bed-rest, went into labor.

"I must maintain a 20-mile radius. I cannot travel beyond that," the former Angel star, 40, said. "If I do, I'll freak – I have to be there if the baby comes."

Now that Bardot is here, David Boreanaz, Jaime Bergman can breathe easy.

"We've been trying to have another baby for a couple of years now so we are beyond excited," Bergman, 33, recently said. "We're over the moon.”

Congratulations to the happy couple.
