It will be the third child in family and Preston, 47, in May prepared for the impending birth by gathering with loved ones for a baby shower bash at the Beverly Hills Peninsula hotel in Los Angeles last week, according to People magazine.
Now the stars’ publicist has confirmed to the magazine that they are expecting a son.
The couple lost their first-born son Jett at the beginning of 2009 after he suffered a seizure and died at the family’s retreat in the Bahamas.
Jett was 16.
They also have a ten-year-old daughter, Ella Bleu.
