"She does crave pickles," the People quoted Aubry, as saying.
"Any bread. Doesn't matter, as long as it's salt and pickles."
"She loves foot massages ... I do all of that stuff," he told Access Hollywood.
The 32-year-old also revealed that he is expecting their first child "sometime around spring".
Aubrey also said that he is 'excited' about the baby.
"Just a new baby and a child in our lives is going to be amazing," he said.
However, the model also revealed that he doesn't know the sex of the baby and will not try to find out that.
"I don't know, and we're not going to find out," he said.
