Kate Middleton is pregnant, and her due date is fast approaching. In preparation, Kate is setting up a playlist to help her during labor, as well as solidifying plans for the big day.

The first child of the Duke and Duchess of Cambridge - aka Prince William and Kate Middleton - has an official due date of July 13,  but some sources say she could give birth as early as next week.

According to E! Online, Kate is "going a bit stir-crazy" in her third trimester and in her free time has made a playlist for when she is ready to give birth.

The Duchess has chosen famous artists and songs to help her nerves in the delivery room.

"She has been filling her iPod with music she wants playing while she's in labor," a source said, E! Online reports. "The other day she downloaded some of Bruno Mars, Calvin Harris and Of Monsters and Men."

Middleton is a big fan of famous artists. At her 2011 royal wedding to Prince William, the royal couple had Ellie Goulding perform at the reception following their ceremony.

The royal baby will be delivered at St. Mary's Hospital in London's Paddington, which is the same hospital where Prince William was born 31 years ago, as well as his brother Prince Harry.

So how will we find out about the baby's arrival? A formal proclamation will be hand-delivered by a royal aide to the palace. At Buckingham Palace, the proclamation will be set up on an easel in front of the palace gates, E! Online reports. Then, a 41-gun salute by the King's Troop Royal Horse Artillery will fire in Green Park.

Kate and William probably plan to debut their child to the world in front of the hospital, to meet the press. Princess Diana did this with Princes William and Harry.
