Tom Selleck is as recognizable for his trademark mustache as he is for his acting talents.
However, the 79-year-old looked worlds away from his usual polished appearance during an outing in Thousand Oaks, California, on Tuesday.
The Blue Bloods star was photographed strolling across a parking lot sporting a bushy gray beard and unkempt hair.
Adding to his casual look, Tom rocked black shorts, a loose-fit black T-shirt, and a navy blue shirt thrown over the top.
The actor is typically pictured looking much more put together with styled hair and a clean-shaven face alongside his well-groomed mustache.
Tom's mustache has become as notorious as him, and while he shaved it off for roles in the early days of his career, his most adored performances have featured him with his now-iconic facial hair.
However, for his role as police commissioner Frank Reagan in Blue Bloods, Tom initially wanted to do it clean-shaven.
"At the time, they had him as the New York City police chief," Tom told People of the role. "That's not the boss in New York, the way it's structured."
He added: "And I said, 'Well, I don't think they can have mustaches, so I'll shave off my mustache,' and [executive producer] Leonard [Goldberg] said, 'Let me check with CBS.' And they said no."
Speaking of his famous 'stache, Tom told The Telegraph: "Look, I was born without it. It's not as important to me as it seems to be to people. And every month or so, it's completely new.
"The hairs have grown out, they've been trimmed. So I don't know, it's something I live with. I don't resent it, but there's more to the work than a mustache."
Tom will soon wrap up his role on Blue Bloods with the long-running NYPD show coming to an end after season 15 has aired this fall.
In November 2023, it was announced that the show had been canceled by CBS.
In May, the actor confirmed that the final eight episodes will form the show's 15th season, rather than part two of the 14th installment.
Following the network's decision to end Blue Bloods, Tom has been particularly vocal about the show's cancelation, calling on CBS to do a U-turn.
Speaking to CBS News earlier this year, Tom was asked if Blue Bloods will end in the fall. "Well, that's a good question. I will continue to think that CBS will come to their senses," he replied.
"We're the third-highest scripted show in all of broadcast. We're winning the night. All the cast wants to come back. And I can tell you this: we aren't sliding off down a cliff. We're doing good shows, and still holding our place. So, I don't know. You tell me!"
In January, Tom had echoed this sentiment in an interview with TV Insider. "CBS will find an awful lot of people aren't ready to say goodbye to it. The show's more popular than ever, and I think [numbers] will increase with the interest this year. We're certainly not out of ideas," he said.
Noting that he's not ready to retire just yet, Tom added: "I'm not counting the days so I can do something else. I love the work. Sometimes the hours are a little harder because I'm older, but so what? I want work as long as they'll have me."
