The royal baby has an official title—before a first name!

Prince William and Kate Middleton welcomed the wee HRH Prince of Cambridge at St. Mary's Hospital in London today, and now that the couple's first child has finally arrived, the world is eagerly waiting for the proud parents to reveal the little one's name.

So when will we know what to call the bundle of joy?

"The name of the baby will be announced in due course," Kensington Palace said in a statement today. Will and Kate will decide when to make the announcement.

While we certainly won't be waiting a full nine months, it may take some time before the proud parents are ready to reveal the child's name, particularly since they did not know the gender of the third in line to the British throne prior to the little one's arrival.

Prince William's own parents, Prince Charles and the late Princess Diana, waited a week before announcing Will's name, while Queen Elizabeth II and Prince Phillip spent an entire month picking out a name for Charles.

The royal baby's name is also particularly important since Will and Kate are naming the future heir to the throne—so don't expect any kooky celeb kid spinoffs to make the cut (sorry, Apple Martin).

"You have to remember they are naming the future king or queen. So you won't want to see something silly, like Queen Suri, which would be fine if you are playing dress-up, but it is not quite appropriate for when you are the queen of 16 nations. They are going to be very careful when naming their child, so we will see something traditional," Victoria Arbiter, ABC's royals contributor and daughter of former Queen Elizabeth II press secretary Dickie Arbiter, told E! News.

Before the baby's arrival, Brits were in a frenzy placing bets on the baby's gender (sorry, to all you folks who bet on a girl) and name.

The current front-runner is George (now that Alexandra is out of the mix) with 11-2 odds. The name, of course, has a long standing tradition with the royal family. Other popular names include James, John and Charles.

The Duke and Duchess of Cambridge welcomed their first child, who weighed in at 8 pounds, 6 ounces, in the Lindo Wing at St. Mary's at 4:24 p.m. local time today.

"Her Royal Highness and her child are both doing well and will remain in hospital overnight," Kensington Palace said in a statement.

"We could not be happier," Prince William added.
