Who is Jakub Mensík’s girlfriend? Meet Josefina Catino who has become a regular presence this year

Jakub Menšík’s remarkable rise over the past 18 months has brought plenty of attention to the young Czech star. His first Masters 1000 title at the 2025 Miami Open, where he defeated his childhood idol Novak Djokovic, announced him as one of tennis’ brightest prospects. His run to the 2026 French Open semifinals only strengthened that belief, especially after overcoming physical struggles that at times left him collapsing on court and exiting matches in a wheelchair. Throughout that journey, one familiar face has remained in the stands: his girlfriend, Josefina Catino, who has become a regular presence during the biggest moments of his career.As Menšík's profile continues to grow, interest in Josefina Catino has followed. The couple reportedly met in 2024 and have been together through the most significant phase of the Czech player's young career. Managing a relationship while competing on the ATP Tour is rarely straightforward, particularly when tournaments stretch across continents for much of the year.Catino, who is from Argentina, has increasingly been part of Menšík's traveling circle. Over the past two seasons, she has appeared at several major clay-court events, including Madrid, Monte Carlo and Rome. Her social media activity has offered a glimpse into that lifestyle, with one post making it clear where her loyalties lie. Referring to the European clay swing, she described "clay season" as her favorite part of the tennis calendar.Her presence was particularly noticeable during Menšík's run in Paris. While the 20-year-old fought through grueling matches to reach this first Grand Slam semi-final, Catino was often posting updates from the tournament giving followers a behind-the-scenes look at the experience.Catino’s online presence is a window into a life that extends far beyond the tennis circuit. By June 2026, she had almost 6500 followers on Instagram, and she regularly posts pictures of her travels, hobbies and everyday life. Her profile bio of “welcome to my overdramatic little world” implies she is a fun, lighthearted person that her audience can relate to.Travel appears to be one of her biggest passions. Her posts feature destinations ranging from the Swiss resort town of St. Moritz, where she enjoyed a ski trip with Menšík, to summer holidays in Greece. She has also documented visits to Miami, including a trip to watch Lionel Messi and Inter Miami CF in action.Animals also hold a special place in her life. One of the stories she posts on her Instagram profile, titled “Amor,” is not about her relationship, but her beloved pets, a dog and two cats.New York seems to stand out of all the places she has been. The clearest insight into a place that holds lasting significance for Catino may have come during the 2025 U.S. Open, when she posted a series of photos from the city and described it as “my dream city with the people i love the most.”
