“They’ve had ups and downs, but now they’re definitely back on,” an insider told People.
They added that the pair are “going strong”.
Martin and Johnson first got together in 2017, one year after the musician finalised his divorce from American actor and businesswoman Gwyneth Paltrow, who he was in a 10-year marriage with and shares two children.
In July 2022, Johnson criticised the Fifty Shades franchise in an interview.
Appearing on the cover of Vanity Fair, the star who found fame through the three R-rated films, shared behind-the-scenes secrets from the popular movies.
The New York Post revealed Johnson, who stared alongside Jamie Dornan in the films, said she “signed up to do a very different version of the film we ended up making”.
“I’m a sexual person, and when I’m interested in something, I want to know so much about it,” she said. “That’s why I did those big naked movies.”
