Taking to X, one fan claimed: “Copycat Meghan strikes again… she’s lightened her hair after Princess Catherine. The irony? Still NOBODY BOTHERS! GIVE IT UP! You can’t ever compete with our Future Queen.”

Another wrote: “Everyone was right… she did in fact lighten her hair straight after Catherine lightened hers.” Several others accused of being "jealous" of the Princess of Wales.

A third pushed back against the frenzy, with one insisting: “The obsession is real but it’s also very creepy.” Others claimed it was "clearly not a coincidence".

Meanwhile, others praised her new lighter silhouette and penned: “Nice to see the duchess looking so well and happy with Harry."

The Duke and Duchess’s rare joint appearance marked their first in five months. Hosted by Kevin Costner, the benefit raised vital funds to support local first responders.

The gathering took place at the actor’s oceanside estate and drew a star-studded crowd, with Oprah Winfrey among the high-profile guests.

Meghan joined Harry briefly on stage, smiling as the couple were warmly received by the audience. At one point, Harry was photographed with his arm around Meghan’s waist, a tender gesture that underscored their united front.

Their appearance ensured Meghan’s new look was firmly in the spotlight, with her hair transformation sparking almost as much conversation as the event itself.

The One805LIVE! benefit has become a fixture on the Californian social calendar, with Harry attending for the third consecutive year.

For Meghan, however, it marked a return to the public stage after maintaining a relatively low profile in recent months. Her presence alongside Harry reaffirmed their ongoing commitment to championing community causes in their adopted Californian home.
