Kate Middleton is having her engagement ring made smaller to fit her finger better, it has been claimed.
The royal bride-to-be has reportedly asked jewellers to alter the ring as she prepares to marry Prince William on April 29.
The sapphire and diamond ring was famously worn by Diana, Princess of Wales.
According to the Sun, Miss Middleton has asked Crown jewellers G Collins and Sons to attach small platinum beads inside the bottom of the ring to make it a size I, which is said to be one notch up from her own finger width.
Miss Middleton appears to have slimmed down in recent weeks as her big day approaches.
The 29-year-old "adores" the ring and "didn't want to cause a fuss", but had found the band was turning on her finger, a royal source told the newspaper.
The source added: "A bride's worse nightmare is looking down and seeing her ring has fallen off.
"One can only imagine how this is magnified when you are marrying the future King of England."
A Clarence House spokesman declined to comment on the claim.
On Monday, the couple visited Lancashire in their last joint engagement before their wedding day.
