If Ellen Degeneres is right, Heidi Klum's fourth child could be a girl!

The talk show host guessed that is what Heidi and Seal's baby would be, and that's what the Project Runway star is secretly hoping for:

"We'd be happy with either, but it would be a lie if I said we weren't hoping for a girl-especially Leni, because she would love to have a little sister."

The happy parents will officially find out what they are having at the end of the month and goes on to say that this baby wasn't exactly planned, but they were not planning either.

Whatever the case may be, Heidi looks spectacular at the Star Trek premiere last night!
