Jason Schwartzman is to become a father for the second time.

The Scott Pilgrim vs. the World star's wife of four years, fashion designer Brady Cunningham, is pregnant with their second child, due early next year. "Brady is due [in April] and she is feeling great. They are not finding out the sex and are keeping the baby's gender a surprise," a source said.

The new arrival will be brother or sister to the couple's first daughter, Marlowe Rivers, two, who is already gearing up to become an older sibling. "Marlowe is super excited about becoming a big sister and they are thrilled to be adding to the family," the source added.

Jason - cousin of actor Nicolas Cage and director Sofia Coppola - has previously said he likes to spoil his wife as much as he can while she's pregnant. "I'm lucky I found a woman that I love and that's amazing. I'm having a family and I feel very happy. I try to be a good father-to-be. I try to treat my wife well so she can enjoy these months," he said.

The 33-year-old star also said before Marlowe was born he purposefully grew a moustache simply so he could laugh at them later in life. "I decided to grow out this moustache, so when we take photos of my girl [she] will be embarrassed," he explained.
