Gisele Bundchen confirmed Friday something we already knew, and were the first to report: She and Tom Brady have a baby girl. The wee one, named Vivian Lake, was born Wednesday night at the couple’s home in Boston. “We feel so lucky to have been able to experience the miracle of birth once again and are forever grateful for the opportunity to be the parents of another little angel,” the Brazilian-born supermodel wrote on her Facebook page. “She is healthy and full of life. Thank you all for your support and well wishes. We wish you and your families many blessings.” (She also posted a picture of the baby’s hand in hers.) No word on whether little Viv was born in the bathtub like her brother Benjamin. (You’ll recall that Gi opted for a water birth with Ben after watching director Abby Epstein’s 2008 documentary, “The Business of Being Born.”) Young Benjamin will celebrate his third birthday Saturday, and Brady also has 5-year-old son, John, with his ex-girlfriend Bridget Moynahan. Bundchen, 32, and Brady, 35, were married in 2009. Gi, who has five sisters, has said she’d like to have a large family. “I’d be lying if I said, ‘No,’ to wanting a lot of kids,” she told Vanity Fair in 2007.
