John Travolta, Kelly Preston Welcome Baby Boy!

John Travolta and Kelly Preston are giving thanks...for their healthy new baby boy!

Their son -- named Benjamin -- was born at an undisclosed Florida hospital on Tuesday, their publicist told UsMagazine.com.

Benjamin Travolta weighed 8 pounds and 3 ounces.

Travolta, 56, Preston, 48 and daughter Ella Bleu, 10, are ""are ecstatic and very happy about the newest member of the family," the rep told Us in a statement.

Mom and child "are healthy and doing beautifully," added the rep.

Benjamin is the third child for the Hollywood couple, who have been married for 19 years. Tragically, their eldest child, son Jett, died in January 2009 at age 16 after suffering a seizure. The couple was then extorted by Bahamian paramedics who first responded to the call.

In June, Kelly Preson's mom, Linda Carlson, told UsMagazine.com that her actress daughter had been "longing for another baby," particularly after Jett's death.

"It's taken [Preston and Travolta] out of such deep grief and made them able to focus on new life," Carlson said. "It just couldn't come at a better time."
