Tom Brady knows how to keep a secret! Just ask Gisele Bündchen, whose husband found out the sex of their baby – due this month – even though she’s waiting on a surprise.

“I’m really the only one that knows at this point,” Tom, 32, said in an interview with 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.”

Especially, Tom adds, because he’s been able to keep it from Gisele, 29. “She’s a very intelligent woman,” he explains. “I wanted to find out and she didn’t, so she said, ‘Go ahead.’ It will be a surprise for her.”

The Patriots quarterback admits that he’s had to be careful with his pronouns as of late. “I always mix it,” he added. “I don’t think I’ve ever slipped. I’m very conscious when I’m saying it.”

So will their nursery at their luxe Boston condo be blue or pink? “There’s no paint yet!” joked Tom, adding that he hasn’t shared yet whether or not his 2-year-old son Jack, with ex Bridget Moynahan, will have to start sharing his hand-me-downs. “Everything is unisex at this point. Yellow. Light green. There’s lots of this.”
