Sarah Michelle Gellar's baby boy has finally arrived! US Weekly revealed that the former Buffy actress and her partner Freddie Prinze Jr have welcomed their new son into the world at some point in the last week, though the exact date has not been confirmed. Their rep told US magazine “Sarah Michelle and Freddie Prinze, Jr. are thrilled to announce that they welcomed a baby son into the world this past week” and added that “mother and baby are doing great.”

Sarah and Freddie haven’t revealed what the little boy’s name will be, just yet. They already have a daughter together – Charlotte – who turned three earlier this month (September 2012) and is reportedly “VERY excited” to be a big sister to the new arrival. News that Sarah Michelle Gellar was pregnant again broke back in April, with a source close to the couple telling US Weekly “She and Freddie are thrilled… They're amazing parents… They still have date nights all the time and have a normal life. They both came of age in Hollywood and love working, but their home life is more important to them."

It looks as though September is going to be a big month for celebrations in this celebrity household: not only will both of their children celebrate their birthdays this month, Sarah and Freddie’s wedding anniversary also falls on September 1. This year marked the couple’s 10th year of marriage and we wish them many more happy years together!
