WATCH: Katie Boulter jokes about making fiancé Alex de Minaur "jealous" with amusing act after Paris triumph

Katie Boulter secured her maiden title on clay at the 2025 Clarins Open on Sunday, May 18, overcoming local favorite Chloe Paquet in three sets in the final. During the trophy ceremony, the Brit mimicked kissing the women's singles trophy while joking that her fiancé, Alex de Minaur, was bound to get "jealous" if he saw what she was up to.

Boulter initially struggled this year with consistency on the WTA Tour since achieving her career-high singles ranking of 23 last November. The 28-year-old had dropped seven of her 13 matches before last week's 2025 Clarins Open.

Katie Boulter played some resilient tennis to nab the title at the 125-level event in Paris, fighting past three Frenchwomen - Chloe Paquet, Varvara Gracheva, and Elsa Jacquemot - in three sets in the final, semifinals, and quarterfinals, respectively. After her triumph, she followed the age-old ritual of kissing the winner's trophy. With several media people clicking her photos, the World No. 38 was quick to joke that her move would likely make her fiancé Alex de Minaur jealous.

"Yeah, just that my fiancé might get jealous though," Katie Boulter remarked while chuckling during the trophy ceremony at the Clarins Open.

Last December, Boulter and de Minaur announced on their Instagram handles that they had gotten engaged, much to the happiness of both their colleagues and tennis fans. In a rather cute picture, the Brit had her arms around the Aussie as she flaunted her engagement ring.
