The most relevant recent Disney princess news I found is about a new princess being reported by Disney rumors coverage, though she is described as having long black hair rather than red hair. For red-haired Disney princesses specifically, recent coverage is mostly about Ariel and Merida: a recent article says Disney is redesigning princess appearances for a new restaurant at Disneyland Paris, and the lineup includes Ariel and Merida.[1][2][10]
What’s new
Disney is reportedly preparing new princess designs for a Paris dining experience, with Ariel and Merida among the confirmed characters mentioned in coverage. Separate recent posts also keep Ariel in the news because fans are still discussing how red her hair looks in live-action and promotional material.[2][8]
Red-haired princesses
Ariel and Merida are the best-known Disney princesses with red hair, and recent stories keep circling back to them rather than introducing a brand-new red-haired princess. Merida’s wild red hair is still widely referenced as part of her character identity.[3][9]
Most likely takeaway
If you meant “latest Disney princess news involving red hair,” the freshest item is the Disney princess redesign story featuring Ariel and Merida. If you meant a brand-new red-haired princess, I did not find a confirmed one in the recent results, only reports of a new princess described with black hair.[10][1][2]
