Gabriel Aubry has been pampering girlfriend Halle Berry through the early stages of pregnancy – massaging her feet and satisfying her food cravings.

"She does crave pickles," he told PEOPLE at Macy's Herald Square in New York for "The World of Calvin Klein" event.

Anything else? Special breads? "Any bread. Doesn't matter, as long as it's salt and pickles," he said.

Berry, 41, and Aubry, 32, are expecting their first child "sometime around spring," he told PEOPLE.

The model – who also owns a Cuban restaurant in New York called Café Fuego – doesn't mind playing the role of chef at home, he's just excited to be a dad.

"Just a new baby and a child in our lives is going to be amazing," Aubry added.

Speaking to Access Hollywood, the first-time father-to-be said he "can't wait to be a daddy" and added that Berry is doing really well.

"She loves foot massages ... I do all of that stuff," he said.

So, will the world's sexiest baby since Shiloh Jolie-Pitt be a boy or a girl? "I don't know, and we're not going to find out," Aubry said.
