Dakota Johnson and Chris Martin Are 'Back On and Going Strong' After 'Ups and Downs' (Exclusive Source)

Dakota Johnson and Chris Martin's relationship is in a good place.

As Johnson, 34, premieres her new movie Daddio at the Tribeca Film Festival in New York City and Martin, 47, continues a world tour with his band Coldplay this summer, a source close to the couple tells PEOPLE the longtime pair are "going strong."

“They’ve had ups and downs, but now they’re definitely back on," the source says.

Johnson and Martin were last seen together during a February trip to Puerto Vallarta, Mexico, where they were spotted hitting the beach. The pair began dating sometime in 2017, three years after Martin and his ex-wife Gwyneth Paltrow famously "consciously uncoupled." They finalized their divorce in 2016.

The pair have typically kept their relationship private over the years. As a source told PEOPLE in March, the couple "got engaged years ago but were in no rush to get married." Johnson was seen wearing a large emerald ring on her left hand in December 2020, though the couple did not comment on the ring at the time.

Martin and Paltrow, 51, were seen in Los Angeles on Thursday, May 30, as they attended their 18-year-old son's high school commencement. Johnson, who has been filming a movie titled Materialists in N.Y.C. in recent weeks, appeared absent from the graduation ceremony; she was photographed filming scenes with her costar Chris Evans the same day as the graduation.

The Coldplay frontman was not seen accompanying Johnson at the Tribeca Film Festival premiere of Daddio, in which Johnson costars with the pair's neighbor Sean Penn. Martin is currently abroad with his band as they embark on a European leg of their world tour. Coldplay is next scheduled to perform in Bucharest on June 12 and is playing in Europe and Australia through November, according to the band's website.

Johnson was seen wearing her emerald ring on her left hand while celebrating her 34th birthday party with Martin in Los Angeles in October and at a Hope for Depression Research Foundation event in November. She did not appear to wear the ring while hosting Saturday Night Live in January. During Johnson's Tribeca Festival appearance on June 10, she did not appear to wear that ring, but instead wore a different dark green ring on her middle finger.

Aside from Daddio, Johnson also stars in the new movie Am I Ok?, which is streaming on Max now.
