John Travolta and Kelly Preston had announced last May that the actress, 47, is expecting a baby.
Their spokesman confirmed to PEOPLE yesterday that it’s a boy. "This is such a healing baby," said a friend of the couple.
In January 2009, the couple’s eldest son, Jett, died following a seizure.
Shortly after they announced the pregnancy, the couple insisted they were not trying to replace their son and that in fact, they had been trying to have another child for years. This new addition to the family was a complete surprise.
The couple had a prenatal party on August 8 for 40 of their closest friends and family.
John Travolta and Kelly Preston also have a daughter, Ella Blue, who is 10 years old and is excited about her new brother.
