Hollyoaks stars Angus Castle-Doughty and Niamh Blackshaw announce engagement, solitaire ring revealed

Angus Castle-Doughty and Niamh Blackshaw have taken their off-screen romance to its next chapter, sharing engagement photos on Instagram after four years together. In the image strip, Blackshaw’s ring is the detail that stops the scroll: a solitaire round-cut diamond set on what appears to be a gold or platinum band.

The design is striking in its restraint. A round brilliant solitaire remains one of the clearest signals in engagement rings because it puts all of the visual weight on the stone itself, with no halo, no side-stone distraction and no ornate metalwork competing for attention. That pared-back look has been a steady favorite among celebrity couples because it photographs cleanly and still feels expensive without trying too hard.

Castle-Doughty, who played Eric Foster on Hollyoaks from 2022 to 2023, and Blackshaw, who portrayed Juliet Nightingale from 2018 to 2023, first met while working on the Channel 4 soap, and their relationship became public in January 2023 through New Year Instagram posts. The engagement news, which surfaced in May 2026, quickly drew warm reactions from co-stars and fans online, adding to the sentimental pull of a pair whose romance grew out of the show itself.

There is also a reason this kind of announcement lands so well with Hollyoaks viewers. The soap has long had a knack for turning cast chemistry into real-life relationships, and that off-screen continuity gives an engagement like this extra resonance. It is not just a celebrity engagement reveal; it is a ring with a backstory, tied to a set, a shared cast history and a relationship that unfolded in public.

What Blackshaw wore fits the moment exactly: a classic solitaire that feels polished, readable and firmly in step with the current preference for rings that look refined from every angle. The photobooth-style frame may have captured the celebration, but the ring itself is what makes the image linger.
