"Honey, I want another baby!" Bursting with joy, new mom KELLY PRESTON informed hubby JOHN TRAVOLTA she's ready for another child – just four months after giving birth to their precious little boy BEN, say sources.

The Hollywood power couple is so in love with parenting, they've decided to have another little Travolta right away – even though John is 57 and Kelly is 48.

"Baby Ben rocked John and Kelly's world and they've never been happier," a longtime family friend told The ENQUIRER. "Neither one can keep their hands off the baby. They're mesmerized by his every coo and gurgle."

Kelly calls the newborn "her little miracle." Following in vitro fertilization, she endured a high-risk pregnancy – but little Ben has been a gorgeous gift who's changed her life.

The actress had been reeling from a broken heart ever since the dark day in 2009 when the couple's 16-year-old autistic son Jett suffered a seizure during a family vacation in the Bahamas and died.

At one point, the couple's emotional agony was so overwhelming, they briefly separated.

Complicating matters, John was accused of frequenting Hollywood gyms and steam rooms to engage in gay sex, as The ENQUIRER was first to reveal.

 "Baby Ben has given them a desperately needed fresh start," declared the source.

Now, the revitalized couple wants to experience the thrill of a new arrival one more time, added the friend.

"Because her pregnancy with Ben was so challenging, Kelly said this time she'd consider a surrogate or even adoption," revealed the source. "Kelly and John both realize that family is all that's really important.

"The only thing that would make them happier is to share their love with one more baby. John is crazy about the idea and told Kelly they should make the project their No. 1 priority."

Meanwhile, the devoted parents also dote on their 10-year-old daughter Ella – who's said to be delighted with her baby brother.

"Ella is totally into her role as big sister," confided the source.

"And now the Travoltas are hoping they'll be expanding the nursery in another year."
