The Duchess of Cambridge had more hospital visitors on Wednesday.
Just two days after husband Prince William, 30, was photographed leaving the King Edward VII Hospital in Central London where a pregnant Kate, 30, was admitted for hyperemesis gravidarum, her sister, Pippa Middleton, brother James and mom Carole (not pictured), also dropped by to keep the mom-to-be company.
Pippa was bundled up in a coat, sporting a tan-colored ensemble, while her brother was casually dressed in jeans and layered tops.
The Palace announced the Duchess’s pregnancy Monday in a statement. “Their Royal Highnesses The Duke and Duchess of Cambridge are very pleased to announce that The Duchess of Cambridge is expecting a baby,” it said. “The Queen, The Duke of Edinburgh, The Prince of Wales, The Duchess of Cornwall and Prince Harry and members of both families are delighted with the news.”
