Delta Goodrem is notoriously private when it comes to her relationship with her boyfriend, Matthew Copley.

And on Saturday, the singer and her beau showed a rare display of affection as they attended the American Express Presents BST Hyde Park event in London.

Delta, 38, wore a black jacket as she leaned close to her boyfriend, who put his arm around her.

She curled her blonde locks and wore a natural makeup palette for the event, which was headlined by pop group Take That that night.

During the show, Delta threw up her hands as she sang along to the group’s greatest hits.

Delta and Matthew first met while on tour in late 2017 and confirmed they were dating in January 2018, but have largely kept their romance a secret.

But Matthew let slip last year that he was madly in love with Australia’s sweetheart.

The guitarist shared a tribute post on Instagram in May to celebrate the final show of Delta’s Bridge over Troubled Dreams tour.

“Words cannot describe the feelings I have for the last show of the tour today! Humble, excited, nervous, sad, proud, nostalgic to name a few,” he began.

Matthew then told Delta how “proud” he was of her and their incredible team.

“I loved every minute of this process and can’t thank you enough for trusting me with the responsibilities and roles I’ve fulfilled with you!” he added.

“This is to take this show worldwide, because the best is yet to come… I love you.”

In 2021, Delta explained that it “feels good” to just keep the details of their romance to themselves.

“I understand that people are interested and I get that. I think that’s a beautiful thing. But [keeping things private] feels good,” she said.

She added that her private life would remain private because she ‘came in’ [the industry] for music and connection and moving lives’, not to be a public figure.
