John Travolta's wife Kelly Preston is counting down the days until she gives birth to her baby boy - because she is "completely ready" for the new family addition.

The Hollywood stars confirmed they were expecting their third child in May (10), just over a year after the tragic death of their 16-year-old son Jett, who died in January 2009 after suffering a seizure.

The couple, who also have 10-year-old daughter Ella, will become parents again before the end of the year (10) - and Preston is excited about her impending motherhood.

She tells, "It's been very easy and so wonderful. I've had no morning sickness and (the pregnancy) has gone by so quickly. I feel terrific.

"John and I are completely ready. My daughter is very excited too. I can't wait for the day to come."
