"Two months into our relationship, Tom told me his ex-girlfriend was pregnant. The very next day, the news was everywhere, and I felt my world had been turned upside down," Gisele revealed in her newly released book, "Lessons: My Path to a Meaningful Life."
Though Gisele never refers to Bridget by name in the book, it's clear she was referring to the fellow model, who Tom dated from 2004 to 2006. In December of 2006, Tom met Gisele via a blind date, and the two began their relationship. Baby Jack was born in August of 2007, meaning he was conceived right around the time Tom met his now-wife.
While the public scandal over Bridget's pregnancy "wasn't an easy time" for Gisele, she did say the ordeal actually helped her relationship with Tom. She said Jack, who's now 11, helped her "heart expand" in a way she didn't know was possible.
"I wanted to be there for Jack and Tom and do whatever I could to create stability in their lives and help them to have a close relationship," she wrote in her memoir, adding that she refers to Jack as her "bonus child."
Jack lives in Los Angeles, and Gisele said the Brady family often FaceTimes him from Boston to say hello, goodnight and everything in between.
Gisele also said Jack inspired her and Tom to start a family because they wanted their children to all be close in age. Gisele and Tom now share Benjamin, 8, and Vivian, 5.
