The 54-year-old actor was seen getting cosy with Sports Illustrated model Penny Lane, 29, as they walked through London’s Primrose Hill.
He looked totally different from his usual action star image.
Lane, who appeared in the Justice League movie, looked very happy and besotted with Butler.
The two were spotted talking and laughing as they walked.
He wore a casual look, which consisted of a white shirt and a flat cap, while she wore black leggings and leather jacket.
They were spotted carrying matching Adidas trainers. They also ordered a couple of drinks at a local establishment.
Lane was named as the 2024 Sports Illustrated Rookie of the Year earlier this year.
Butler, who was previously in a relationship with Morgan Brown, started to act as a Spartan in 300.
He has a huge list of former flames, including Naomi Campbell, Jennifer Aniston, and Jessica Biel.
