Will Harriet Sperling Wear a Royal Tiara? The Rule That Could Change Everything at Peter Phillips' Wedding

Picture the scene: a June wedding at a picture-perfect Cotswolds church, and a bride walking down the aisle. But will that bride be wearing a crown worth a small fortune — or nothing at all?

When Peter Phillips marries NHS nurse Harriet Sperling at All Saints Church in Kemble, Cirencester on 6 June, it'll be a decidedly un-royal royal wedding. Peter has no title — his mother Princess Anne famously turned down the offer when he was born in 1977.

That means Harriet won't become a princess or gain any aristocratic styling when she says "I do." She doesn't carry a hereditary title of her own either. So the tiara question becomes genuinely complicated.

Here's the twist — we've been here before. When Peter married his first wife, Autumn Kelly, in 2008, Autumn had no title either. And yet she walked down the aisle wearing a tiara. A royal tiara, no less.

Anne simply lent it to her daughter-in-law. One generous gesture, and the tiara question was settled.

Peter's sister Zara also has no royal title, yet she wore Princess Andrew's Meander Tiara — valued at an eye-watering £280,000 — when she married Mike Tindall in 2011. The piece dates back to photographs of Princess Alice wearing it as far back as 1914.

The pattern is becoming rather clear. This family doesn't let a missing title get in the way of a spectacular wedding-day moment.

For her own first wedding in 1973, Anne wore Queen Mary's Fringe Tiara — borrowed from her grandmother, the Queen Mother. It was her something borrowed. When she married Sir Timothy Laurence in 1992, she skipped the tiara entirely, choosing flowers instead.

With precedent firmly on Harriet's side, all eyes are now on Princess Anne. One loan from her jewellery collection, and a bride who isn't technically royal could still have her fairytale crown moment.

We have a feeling Anne will come through.
