Diane Keaton wraps up in puffer coat and rocks her trademark hat during walk with beloved dog Reggie in LA

Diane Keaton stepped out with her four-legged friend on Saturday for a casual stroll through her Brentwood neighborhood in Los Angeles.

And as always, the actress, 78, showed off her unique sense of style, wearing a puffer coat and bowler hat.

Underneath, the Godfather star wore a black turtleneck, blue jeans and chunky black boots.

The star – who recently visited Ariana Madix and Katie Maloney’s new sandwich shop – completed the outfit with a pair of glasses.

Her beloved pet Reggie was actually a gift from a friend who thought she needed some company after the second of her two children left home, making Keaton an official empty nester.

After claiming she is now no longer dating, the Academy Award-winning actress is now calling Reggie more than just a top dog companion.

“I didn’t even ask about her,” she said during a conversation about the golden beauty AARP the magazine.

“He came to me and said, ‘I think you need this dog.’”

I was like, “Okay, I guess?” Of course I just love her now. Dogs are irresistible. They’re just idiots. Reggie is a huge jerk, and she’s a great jerk, and she’s hilarious.’

Reggie, a Labrador Retreiver, joined the family as an adoption in 2020 and Keaton showed her off as much as possible to her 2.5 million Instagram fans and followers.

‘THIS IS MY NEW DOG, REGGIE!!! IS SHE HALF HORSE OR HALF DOG? MAYBE SHE’S INSANE! I love her!’ the acclaimed actress wrote, referencing her skipping through weeds and tall grass, when introducing her on social media in October 2020.

In those four years, the beautiful golden dog has even become the star of her Instagram feed, reaching the 2.5 million mark on Instagram.

“Reggie is the boss of the house!” Keaton, 78, revealed.

“She has beds in every room, so I thought, ‘Why not create one that’s Reggie-approved in our line?'” the Father of the Bride star said of her collaboration with the homeware brand Hudson Grace.

Not only are there beds, but the line of dog goods also includes bowls, treat tins and even a door stopper, which bears a striking resemblance to Keaton’s prized dog.

Keaton was 50 years old when she decided to become a mother and adopted her daughter Dexter, 27, in 1996 and son Duke, 22, in 2001.

She was perhaps one of the most popular and critically acclaimed actresses of the 1970s and 1980s, appearing in a number of critically acclaimed films, as well as films that were mainstream and popular.

The Los Angeles native started her career on stage, but eventually made the transition to the big screen in the romantic comedy Lovers and Other Strangers (1970).

Keaton's stellar film career included her Oscar-winning performance in Annie Hall (1977) alongside writer and director Woody Allen, with whom she also dated.

She also made waves with her roles in a number of Woody Allen films such as Play It Again, Sam (1972), Sleeper (1973) and Annie Hall (1977), for which she won an Oscar for Best Actress.
