The Relationship Timeline

Their story began when Costello, a long-time admirer of Krall's work, approached her in 2002. Despite their ten-year age difference and vastly different musical backgrounds, they quickly connected. The couple married on December 6, 2003, in a private ceremony held at the estate of their friend, Sir Elton John, near London. This union marked a significant new chapter for both artists, leading to a profound creative partnership that would soon manifest in Krall’s music.

The Girl in the Other Room: A Unique Musical Collaboration

While fans often hope for a full-scale joint album, the most significant musical collaboration between Diana Krall and Elvis Costello remains Krall’s 2004 album, *The Girl in the Other Room*. This album is a crucial piece of their shared artistic history and a key entity for topical authority.

The project was a profound departure for Krall. Up until that point, her albums were primarily composed of jazz standards and covers, solidifying her reputation as a master interpreter. *The Girl in the Other Room* marked the first time Krall included original material, co-writing six songs with her new husband.

The lyrical contributions from Costello were deeply personal, reflecting on the recent loss of Krall’s mother and their burgeoning relationship. The collaboration allowed Krall to move beyond her established persona, demonstrating her abilities as a songwriter and a more complex artist.

Key tracks from this collaboration include:

• "The Girl in the Other Room": The title track, a bluesy, introspective piece.
• "Departure Bay": A poignant, reflective song named after a ferry terminal in Krall’s hometown of Nanaimo, British Columbia, capturing themes of home and loss.
• "Narrow Daylight": A track showcasing the blend of Krall’s piano elegance with Costello’s lyrical depth.

Although they have not released a subsequent album of original co-written material since, the shadow of *The Girl in the Other Room* looms large, proving that their personal partnership was capable of producing a singular, critically acclaimed artistic statement.

Life with Nearly Adult Twins: Dexter and Frank in 2025

Perhaps the most significant and private aspect of their life together is their role as parents. The couple welcomed fraternal twin sons, Dexter Henry Lorcan and Frank Harlan James, on December 6, 2006, exactly three years after their wedding day.

As of late 2025, Dexter and Frank are nearly 19 years old, a milestone that marks a major transition for the family. The presence of their children has been cited by Costello as a source of domestic stability, a contrast to his earlier, more tumultuous years in the music industry.

The couple has been fiercely protective of their sons' privacy, allowing them to grow up outside the intense spotlight that follows their parents. This commitment to a normal family life, primarily split between their homes in Manhattan and Canada, is a testament to their focus on stability over celebrity.

Balancing Tour Life and Parenthood

The demands of a global career, particularly in 2025 where both artists are still actively touring—Diana Krall with her June 2025 Detroit show and Elvis Costello with his 2025 tour dates—require careful coordination.

• Krall’s Perspective: Krall has often spoken about the challenges of touring while raising children, emphasizing the importance of keeping their lives as normal as possible.
• Costello’s Evolution: Costello, who once seemed to embody an anxious, distrustful persona, has found a contentment in domestic bliss, a transformation he attributes to his marriage and fatherhood.

Their ability to maintain a successful, two-decade-long marriage in the high-pressure world of music, while raising twin sons who are now on the cusp of university age, is a remarkable achievement. They represent a rare model of celebrity partnership where mutual respect for separate artistic careers and a shared priority for family life have created an enduring harmony.

The Enduring Legacy: Separate Paths, Shared Journey

The story of Diana Krall and Elvis Costello is ultimately one of complementary opposites. Krall’s world of cool, sophisticated jazz piano and standards meets Costello’s fiery, genre-hopping rock and roll. This contrast, rather than creating friction, seems to have provided a creative and personal anchor for both.

Their professional lives continue to thrive independently. Krall’s legacy is secured by her mastery of the Great American Songbook, while Costello remains one of rock’s most celebrated and prolific songwriters, constantly exploring new musical territory. The few instances where their paths have crossed musically, most notably on *The Girl in the Other Room*, serve as powerful reminders of the magic that happens when their distinct talents merge.

As they navigate their third decade of marriage and their sons begin their own adult lives, Diana Krall and Elvis Costello continue to define what it means to be a modern musical power couple: two immense talents supporting each other while remaining true to their unique, individual artistic visions.
