Why wasn't Kate Middleton wearing her engagement ring last week?
Don't worry, she and Will aren't on the rocks.
We're big fans of her style here but there was one thing Kate Middleton always wears that was notably absent during an outing last week - her engagement ring.
Kate made an official royal visit to Great Ormond Street children's hospital in London last Wednesday wearing a ruby red coat and an understated black clutch and sporting the smallest hint of a baby bump but was without her trademark sapphire bauble.
Not to worry though as Cosmo has looked into it and it doesn't mean anything for her marriage - she left it at home for hygiene reasons.
Kensington Palace told the publication that the ring's "intricate nature" (is that code for the fact that it's huge?) meant it could have carried bacteria into the hospital.
Given the fact that she was visiting seriously ill kids, it was probably best that she minimise any risk and not wear it.
It's rare for Kate to go without the piece of jewellery that's become her trademark.
The ring carries significant meaning for both her and her husband as it once belonged to his mum Lady Diana.
Diana actually chose the ring for herself from a section presented to her by Prince Charles, though that in itself caused a scandal, according to The Diamond Store, as a royal bride was expected to have her ring custom-made.
