Bode Miller and wife Morgan's family is growing by four feet.
The couple announced on Monday's episode of Today that they are expecting identical twin boys - something Morgan admitted was "completely" a shock for the couple.
"From the beginning of our relationship, [Bode] always said, 'I want identical twin boys, born on my birthday,' " she said. "And this time, when we found out I was pregnant, I said, 'Do you think it's twins this time?' And he said 'No.' "
The soon-to-be mother of twins explained that she went to her ultrasound appointment alone, which is where she was surprised to learn that she was expecting not one but two babies.
"Sure enough, identical twin boys," she added in the spouses' interview with Savannah Guthrie, going on to reveal in an Instagram post that the twins are due on Nov. 11 - almost one month to the day after Bode's birthday.
The Olympic skier, 41, and Morgan, 32, are already parents to sons Easton Vaughn Rek, 10 months, and Nash Skan, 4. Bode is also dad to son Samuel Bode, 6, and daughter Neesyn Dacey, 11.
The pregnancy announcement comes over a year after the couple's loss of their 19-month-old daughter, Emeline Grier, who died in a tragic drowning accident.
