Paul Anthony Kelly, the star of the hit series Love Story, has opened up about the remarkable transformation he underwent to play the iconic role of John F. Kennedy Jr. The actor, who spent two decades as an international model before landing the part, detailed the extreme physical changes required to embody the famous figure.
A Drastic Physical Overhaul
Kelly, 37, revealed that he had to gain two suit sizes in just three weeks to match Kennedy's more muscular frame, a stark contrast to his lean, runway-ready body. He embarked on heavy lifting workouts focused on his chest and back, hitting the gym daily at 4:30 a.m. after learning he had won the role only weeks before filming began in New York for the Ryan Murphy-produced FX/Hulu show.
Covering Up and Adding On
In addition to bulking up, Kelly's extensive tattoo collection posed a significant challenge. Makeup artists on set spent over an hour each day covering his inkings to maintain the character's clean-cut appearance. The transformation also included subtle hair adjustments, with Kelly having "two very small pieces" added to his locks daily to match JFK Jr.'s thicker hairline, as he admitted, "I'm getting older. My hairline is not as thick and prominent as John-John's."
From Runway to Acting Success
Kelly's portrayal has earned praise from fans and critics alike, particularly impressive given his limited acting experience. Before Love Story, his only credit was a minor role in two episodes of the Canadian TV drama Body Language from 2008–2010. He spent ten years auditioning to transition from modeling to acting, making his breakthrough with this high-profile role.
A Monumental Personal Milestone
The day Kelly received his producer callback for Love Story coincided with life-changing personal news. During a December 2025 interview with Interview Magazine, he shared that it was also the day he and his wife, Syd Widziszewski-Kelly, discovered they were expecting their first child. "I do the Zoom, and right before we're about to go for dinner for our second wedding anniversary, she tells me we're pregnant," Kelly recalled, noting that "May 1st was a big day."
Balancing Privacy and Public Life
Despite his rising fame, Kelly has kept details about his family life private, only confirming parenthood during a recent appearance on The Kelly Clarkson Show. However, he has publicly celebrated his marriage, sharing an Instagram carousel dedicated to Syd two weeks after Love Story's premiere with the caption, "Couldn’t live life without you. To forever and ever-again. xo." Fans have praised his devotion, with one commenting, "We love a man who makes his woman feel secure and shows her off as he’s becoming America's boyfriend."
Instagram photos show Kelly's relaxed day-to-day life in Portland, where he sports shaggy hair and a nose ring, contrasting sharply with his polished on-screen persona. After filming wrapped, he and Syd planned to return to Portland to "start nesting" in preparation for their baby's due date on January 7.
Kelly's journey from model to acclaimed actor, coupled with his personal milestones, highlights the dedication and sacrifice behind his compelling performance as John F. Kennedy Jr. in Love Story.
