Kate Middleton made a surprise fashion statement during her latest royal appearance.

The Princess of Wales visited a male prison in Surrey, England, on Tuesday in support of an addiction charity and was seen with medical tape on her right hand.

According to People, Middleton injured her hand while playing on a trampoline with her children, Prince George, 10; Princess Charlotte, 8; and Prince Louis, 5.

The outlet reported a spokesperson confirmed it is "a small injury, nothing serious."
