Penelope Cruz says that she loves breast-feeding her children. The Spanish actress nursed her son Leonardo, and plans to continue with her daughter, five-month-old Luna.

"I was breast-feeding my son 13 months, and I plan to do the same with my daughter," she told Allure magazine. "[Nursing] is addictive. It's hard when the day comes when you have to stop."

39-year-old Cruz, who is married to Spanish actor Javier Bardem, also revealed her nickname for her close friend Salma Hayek.

"She's one of my best friends. We call each other huevos [eggs]," Cruz said. "It was because when we were working together, we didn't have children yet, so we used to sleep much more than now. So it was a way to call each other lazy.

"We slept in the same bed so many times and it was like she was always trying to wake me up and call me huevos."
