Prince William, Kate Middleton and baby George

Prince William and Kate Middleton picked seven people to serve as godparents to 3-month-old Prince George, but the couple's siblings, Prince Harry and Pippa Middleton, are not among the chosen, People reports.

The names of the seven were released a few hours before George's Christening, which will take place at 10 a.m. ET at the Chapel Royal in St. Jame's Palace, led by the Archbishop of Canterbury Justin Welby.

Which bubble shows will survive?

While Harry and Pippa didn't make the list, Olympic equestrian and William's cousin Zara Philips ( who's married to rugby player Mike Tindall) will serve as George's godmother alongside Emilia Jardine-Paterson, Katie's friend from Marloborough College and Julia Samuel, a close friend of Princess Diana's. Oliver Baker, a friend from St. Andrews University; Earl "Huge Grosvenor, the heir to the Duke of Westminster; Jamie Lowther-Pinkerton, their Principal Private Secretary and Equerry and William van Cutsem, a childhood friend of William, round out the list of godparents.
