"She has stopped with her lessons. She stopped before Thanksgiving," says Keith Douglass, president of Shoreline Aviation, which provided the model with her copter lessons. "She's waiting to have the baby and then she's going to start up when things settle down again."
Bündchen, 29, who passed the required written exam last month, only had her in-flight test left to go before she would become a pilot, but Douglass says she didn't mind putting her aviation dreams on a brief hold. "She took it in stride," he says. "She pretty much knew she would have to stop when she got close to her due date."
Now, "she'll have to review when she starts again. But it got to be time to take a break. She'll probably start again in January. She can't wait to take her family for a ride in the helicopter."
In the meantime, she's been busy preparing for her new baby, while husband Tom Brady, 32, finishes up his season with the New England Patriots.
"She is taking some time to get ready to have a family," says Douglass. That includes decorating a nursery in neutral colors like yellow and green at the couple's Boston condominium. (The supermodel has said she doesn't want to know the sex of the baby – even though her husband is already aware.)
"She's in full-on nesting mode," adds a source. "She's not going out much any more. She’s just working on getting ready for the baby. She's extremely happy and excited to become a mother."
