Mel Gibson made a casual appearance at Vince Vaughn's Hollywood Walk of Fame ceremony, looking unrecognizable at 68 with gray hair and a scruffy beard. Dressed in a wrinkled white polo shirt, knee-length ombre blue shorts, and black sneakers, Gibson's laid-back look contrasted sharply with the more formal attire of other attendees. The event celebrated Vaughn, 54, who received a star and posed with his family, while Gibson, a longtime friend, humorously interrupted the ceremony by pretending to take selfies with Vaughn. Their friendship dates back to their collaboration in the 2018 film 'Dragged Across Concrete'. As Gibson snapped selfies, glimpses of his driver’s license and Visa card were visible, adding a personal touch to the event. Vaughn's upcoming series 'Bad Monkey' was also highlighted, showcasing his latest career milestones.
