John Travolta and his wife Kelly Preston proudly showed off their newest addition to the A-list family, son Benjamin Hunter Kaleo, on the cover of the new Hello! magazine, and RadarOnline.com has all the scoop for you.

The Pulp Fiction star, 56, told the magazine "it's been uplifting" to spend time with his infant son, "especially when he smiles at me and seems contented in my arms.

“He's given the house a renewed spirit and purpose," Travolta said.

The couple also said that Benjamin's sister, 10-year-old Ella Bleu, has been quite the "mommy's helper" since the baby arrived November 23, 2010, weighing a healthy 8 lbs., 3 oz at birth.

Benjamin's the third child for Travolta and Preston, 48. The family looks to be on the road to recovery just more than two years after the tragic death of their beloved son Jett, who died at the age of 16 in January 2009 from a seizure at the family's vacation home on Grand Bahama island.
