Tom Selleck, 79, was recently spotted in Thousand Oaks, California, looking significantly different from his 80s prime, sporting a bushy gray beard and casual attire. This appearance follows the cancellation of his series Blue Bloods, which has reportedly left him disappointed. Observers noted large vertical scars on both of his knees, leading to speculation about recent knee surgery, although Selleck has not publicly confirmed any medical procedures. His representatives have consistently denied claims regarding his health, stating he is 'fit and vigorous' and refuting rumors of a secret medical crisis. Selleck has returned to his California ranch with his wife, Jillie, after years of commuting for filming. The cancellation of Blue Bloods has shifted CBS's programming focus, leading to the introduction of new shows.
