Why is Tom Brady's son named monyhan?

Answer 1

Bridget and Tom were never married. When Bridget was pregnant, Tom was completely un-supportive of Bridget, having already moved on datin Gisele Bundchen. Since Jack Moynahan lives full time with Bridget and only visits Tom on the weekends and holidays, Bridget probably felt that it was more appropriate and easier for Jack to have her last name. It makes it easier for traveling, school, insurance, etc to have her name than his, given she is the full-time custodial parent.
