The pair made their official debut at the An Unforgettable Evening event on April 28, 2025, which supported breast cancer research. Their relationship is still fresh, but Kloots shared that it’s been “absolutely lovely,” while Gimelstob added, “She’s just an incredibly special person… so classy and has so much grace.”

Early Life & Career in Tennis

Justin Gimelstob began playing tennis at age 8 with his brothers and later played professionally from 1996 to 2007. A standout moment in his career came in 1998, when he won the Australian Open and French Open mixed doubles titles with Venus Williams. After retiring, he became a tennis commentator and served on the ATP Board of Directors. However, in 2019, following a no-contest plea to a felony battery charge, he stepped down from the board, citing he had become a “distraction and a liability.”

The former couple shares a son, Brandon, born in 2013. Gimelstob is a hands-on father and even coaches his son’s baseball team.

How He Met Amanda Kloots

Amanda Kloots met with her boyfriend at a Formula 1 race in Las Vegas. Although they were both in other relationships at the time, they reconnected later. “We played a little tennis as friends,” said Gimelstob. With the help of mutual friends, they eventually went on their first date about a year and a half later.

While Gimelstob’s exact net worth isn’t publicly confirmed, his earnings from a successful tennis career, media work, and nonprofit activities likely place it in the multimillion-dollar range.
