On Saturday, January 24, a day after Alex de Minaur’s third-round win over Frances Tiafoe, Katie Boulter shared a photo on Instagram from the Australian Open. The 29-year-old British player looked elegant and relaxed as she supported her fiancé from the stands.

Katie Boulter added a fun caption to the post. She wrote, “51% shareholder ��.” The line was a playful response to former tennis star Jim Courier. Courier had joked that de Minaur would become a “49% shareholder” in their marriage during on-court talk after the match.

The post quickly drew comments from top names in women’s tennis. Retired Canadian player Eugenie Bouchard left the most talked-about reaction. She wrote, “Kate Middleton vibes.” The comment compared Boulter’s look to Catherine, Princess of Wales, and fans loved it.

Emma Raducanu also reacted with a heart-eyes emoji, “��.” Ukrainian player Marta Kostyuk followed with a warm message, writing, “Beautiful ����.” Their responses helped push the moment across social media.

Later, Alex de Minaur spoke about wedding planning after the match. He said, “Honestly, the fact that we’re both tennis players and we’ve both got quite a busy schedule helps. We are doing as much as we can together.” He added, “I’m sure when it comes to the details of napkins and flowers and decoration purposes, that’s not my forte. I’ll leave that to Katie.”

On court, Alex de Minaur kept moving forward. He beat Alexander Bublik in the fourth round to reach the quarterfinals. His next match will be tough, as he is set to face Carlos Alcaraz. De Minaur has lost all five of his past matches against the Spanish star.
