Model mama Eva Herzigová is expanding her family.
The Czech beauty is four months pregnant with her second child with partner Gregorio Marsiaj. The new baby, due next spring, will join big brother George, 3.
“Gregorio and I are thrilled with the wonderful news,” Herzigová tells PEOPLE exclusively. “Our son George is being really sweet, asking all different questions about the baby and talking to my belly.”
The model, 37, was spotted shopping for her new arrival on Monday at a Bonpoint boutique in London.
