Brazilian supermodel Gisele Bundchen admitted recently that she had a very difficult time keeping her wedding day a secret. She and Patriots quarterback Tom Brady had a small California ceremony in February, and reaffirmed their vows in April in Costa Rico. "We tried very hard to keep it private. Oh my God, you have no idea how hard that was. But it was worth it, we had a great time. I think we were very lucky," Bundchen said. "I think I'm the happiest person. You know what the secret to being happy is? Being grateful. And I'm very grateful."
