JFK’s grandson just made his acting debut in ‘Blue Bloods’

The Harvard Law student said it was his "dream come true."

Jack Schlossberg, the only grandson of the late President John F. Kennedy, can now officially call himself a TV actor.

The 25-year-old Harvard Law School student appeared in the eighth season finale of the CBS drama “Blue Bloods” Friday night, playing Officer Jack Hammer.

“I don’t make the rules, I just pretend to enforce them — Cash me tonight on season 8 finale of Blue Bloods my dream come true!! Best show in the entire world,” Schlossberg captioned two behind-the-scenes Instagram photos.

In one of the photos, he poses with his mother, Caroline Kennedy, “Blue Bloods” stars Will Estes and Vanessa Ray, and executive producer Kevin Wade. In another, Schlossberg stands in front of a sign with his character’s name on it.
