Kate & William Introduce Their Princess

She's not even 11 hours old, and the royal princess is already making her public debut.

Kate Middleton and Prince William presented their newborn daughter to crowds gathered outside St Mary's Hospital just moments ago, BBC News reports. The infant was swaddled in a white blanket and cap as she slept in her mother's arms. Kate, meanwhile, chose a yellow floral-print dress and taupe heels (heels?!).

The Duke and Duchess of Cambridge then departed for Kensington Palace with their new addition, who joins big brother Prince George. The royal baby girl had a meeting with little George earlier in the day. 

Prince William took his nearly two-year-old son to meet his new sister just hours after her birth. Father and son donned matching blue sweaters, white button-downs, and deep side parts for the occasion. Looks like Georgie has also been practicing his royal wave for the commoners.

So, yeah, it's quite the photogenic family. Can't wait for the Christmas card.
