Johnson's attendance at Martin's latest gig came about after a source recently told PEOPLE that the couple's relationship is in a good place.

“They’ve had ups and downs, but now they’re definitely back on," the source said, adding that the duo is "going strong."

Johnson and Martin have typically kept their relationship private over the years. A source told PEOPLE in March that the couple "got engaged years ago but were in no rush to get married."

They began dating sometime in 2017, three years after Martin and his ex-wife Gwyneth Paltrow famously "consciously uncoupled." (They finalized their divorce in 2016.)
