The pair has been linked since 2018.
Is Dakota Johnson a bride-to-be? The question started circulating after the 31-year-old actress was spotted sporting what appeared to an engagement ring. Johnson has been romantically linked to 43-year-old Chris Martin since 2018.
In photos taken on Dec. 11, the Fifty Shades of Grey star is seen wearing a large emerald rock on that finger while out shopping in West Hollywood.
ET has reached out to Johnson's rep for comment on the engagement speculation.
Martin and Johnson first sparked relationship rumors in early 2018, but have kept their relationship private. In September 2018, the actress told Tatler that she was "not going to talk about it," before adding, "but I am very happy."
Martin was previously married to Gwyneth Paltrow, with whom he's maintained a friendship, and the two share two children, 16-year-old Apple and 14-year-old Moses. Paltrow has made headlines for being so close to her ex's girlfriend and possible now-fiancee.
"I love her," Paltrow told Harper's Bazaar of Johnson earlier this year. "I can see how it would seem weird because it's sort of unconventional. But I think, in this case, just having passed through it iteratively, I just adore her."
