Teenage tennis hopeful Cruz Hewitt, son of Australian legend Lleyton Hewitt, was observed with Myla Federer, one of Roger Federer's twin daughters, at the US Open in New York.

The pair, both 17, were seated together in the stands during an evening match on Monday, appearing engaged in conversation and sharing smiles. They were seen looking at their phones and leaning in together during a friendly moment.

Myla's twin sister Charlene and younger brother Leo were also present at the event, watching American Ben Shelton's first-round victory.

This sighting follows previous public appearances of Cruz with the Federer twins, including at the Australian Open in January and Wimbledon in recent months. These joint appearances have sparked considerable interest and rumors about a potential romance between Cruz and Myla, given their prominent tennis pedigrees.

An insider told Woman's Day that a close friendship between Cruz and Myla, who have known each other for some time, would be unsurprising. "If they are really an item, then for both sets of parents, it would be a relief of sorts because they each know that they have grown up together with very similar values," the insider added.

Speculation about Cruz's future includes a potential move to Switzerland to train. The twins reside there with their father, and Cruz reportedly sees an advantage in being mentored by Federer and remaining close to his friends. "The Federers adore him and Cruz thinks it could be a win-win. Be close to the girls but also have Roger as a mentor," the insider noted.

However, Cruz's parents, Lleyton and Bec Hewitt, are reportedly cautious about him moving abroad. They are concerned that potential distractions could impact his tennis training. Lleyton Hewitt, a veteran of the professional tennis circuit, understands the excitement of such a move but also recognizes the challenges. "He's not shutting the door on Switzerland, but he wants Cruz to earn the right to make those big decisions by putting the work in first," the insider stated.

Lleyton Hewitt has previously spoken about the demanding nature of their family's lifestyle, acknowledging the significant role his wife, Bec, played in managing the family's relocations for his career and their son's burgeoning tennis journey. He credited her with being the family's anchor during their extensive travels.
