HOLLYWOOD, Calif. — John Travolta and Kelly Preston are seeing baby blue.

The longtime couple, who previously announced they had another baby on the way, will soon welcome a son, a rep for the actress tells Star magazine.

Earlier this month, the twosome celebrated the news by holding a baby shower.

Travolta, 56, and Preston, 47, announced the pregnancy back in May, more than a year after the tragic death of their 16-year-old son Jett, who died after suffering a seizure at the family's vacation home in the Bahamas.

"It's impossible to keep a secret ... especially one as wonderful as this," they said in a statement posted on their respective Web sites. "We want to be the first to share this great news with everyone that we are expecting a new addition to our family."

The couple's soon-to-be-born baby boy will join older sister Ella Bleu, 10.
