While Bündchen has remained mum on the details, a source says the child's middle name is River. The moniker reflects the water-themed middle names the star gave her two older children, whom she shares with ex-husband Tom Brady: son Benjamin Rein, 15, and daughter Vivian Lake, 12. (Bündchen also considers herself a "bonus mom" to Brady's son Jack, 17, whom he shares with ex Bridget Moynahan.)
