The duchess, 32, was supposed to accompany her hubby, also 32, at the opening of the China Centre at Oxford University Monday. However, because she is suffering from Hyperemesis Gravidarum (as she did during her first pregnancy), she had to cancel, and Prince George's father went solo to this royal engagement.
William was all smiles, though, as well-wishers greeted him outside the center. The prince said he was "thrilled" about his and Kate's baby news, adding, however, that it's been "a difficult few days." He also addressed those at the opening of the center Kate "is sorry to miss it [the opening], and she hopes to come back in the future to meet you all for herself."
