Kristie Mewis has given fans a glimpse into the lighter side of parenthood with fiancée Sam Kerr, revealing the affectionate name the couple use for their infant son, Jagger. The USWNT midfielder shared the Kristie Mewis baby nickname—”Mr. Moo Moo”—in a social media post, offering a warm counterpoint to Kerr’s recent on-field milestone with Chelsea.
A nickname with a cheeky twist
In the caption of a showing herself and Jagger at Stamford Bridge, where they watched Kerr play for Chelsea, Mewis disclosed the couple’s pet name for their son. She also encouraged her followers to share their own amusing nicknames for their children. Kerr, never one to miss a comedic beat, responded with a less sentimental alternative: “Mr. sh**througheverything,” a description that many parents of young infants will recognize all too well.
The exchange, played out publicly, highlights the couple’s comfort with sharing both tender and humorous moments of family life. Mewis, 34, gave birth to Jagger in May, and the pair have been open about their relationship since going public in 2021.
From pandemic beginnings to engagement

Mewis and Kerr began dating in 2020, during the COVID-19 pandemic, and announced their engagement in November 2023. Over the years, they have spoken candidly about their visibility as a same-sex couple in professional sports. In an interview with Gaffer before their engagement, Mewis explained why she values being open about their relationship.
She said that simply being out and being two women in love could potentially change how one or two people feel about themselves or their own relationships. Mewis added that she enjoys sharing her relationship on social media, noting that if their happiness as an out gay couple can help others feel more positive about their own lives, that is deeply meaningful to her.
Balancing football and family
Kerr, meanwhile, recently reached a significant career landmark by scoring her 100th goal for Chelsea. The couple’s shared moments—whether celebrating Kerr’s achievements on the pitch or posting about their son’s nicknames—offer a window into their life together. The at Stamford Bridge captured that balance: a family moment set against the backdrop of a major football fixture.
While the nickname “Mr. Moo Moo” may be the one that sticks in the public imagination, Kerr’s cheekier version serves as a reminder that parenting is rarely glamorous. For Mewis and Kerr, sharing both the sweet and the messy appears to be part of the deal.
