He's getting so big!

Kelly Preston hung out in NYC on Monday with a very special little guy: Benjamin Hunter Kaleo Travolta!

The actress, 48, enjoyed the summer-like weather in the Big Apple with her little boy, whom she and husband John Travolta welcomed back in November.

Benjamin joins big sister Ella Bleu, 10. Back in January, Preston told reporters at a Hollywood event that her son is "identical" to his famous dad, 57. "Maybe there's me somewhere in there, but he looks so much like his daddy," she gushed.

Travolta added that Benjamin is "a miracle."

The Hollywood couple conceived Benjamin one-and-half years after the seizure-related death of their son Jett at age 16.

"He's brought us a new beginning," the duo told HELLO! magazine. "He is the best gift we could possibly have."
