Tom Brady clearly doesn't like surprises!

The Patriots quarterback, 32, found out the gender of his baby -- due in December -- even though wife Gisele Bundchen is waiting.

"I'm really the only one that knows at this point," he told Boston's WEEI Sports Radio on Wednesday. "My dad asked me. I haven't told him. [Gisele] doesn't know. It's a pretty good feeling knowing something that no one else knows."

Brady -- who is already father to son John, 2, with ex Bridget Moynahan -- said Bundchen didn't have a problem with his request to find out in advance.

"She's a very intelligent woman. I wanted to find out and she didn't, so she said, 'Go ahead,'" he said. "It will be a surprise for her."

His trick to keeping the secret?

"I always mix it," he said of his use of boy and girl pronouns. "I don't think I've ever slipped. I'm very conscious when I'm saying it."
