Gisele Bundchen is pregnant again, and is expecting her second child with her husband New England Patriots quarterback Tom Brady, Us Weekly reported cutting an anonymous source.

"Yes, she is pregnant," the source told Us Weekly, adding that the31-year-old Brazilian supermodel is three months along. "They are really happy!"

Earlier rumors had emerged that the Bundchen was sporting a tiny baby bump, but the couple have not confirmed the pregnancy news.

The couple, who got married in February 2009, has a two-year-old son named Bejamin.

Brady, 34, also has another four-year-old son, John, from a previous relationship with actress Bridget Moynahan. They had dated from 2004 to late 2006.

Bundchen has expressed her desire to have more children in 2010.

"I want more kids for sure, but I don't know when," she told British Vogue, adding that she had her “hands full" with her son and stepson.

"For Benjamin, his big brother is his hero," said the model. "Jack comes in and Benjamin has a big smile. He wants to follow him around. Anything he does, he's just in awe of him like, 'Oh my God!'"
