As Kate Middleton due date nears, a new report has indicated the type of music she will listen to during the delivery of her royal baby. 

According to OK! magazine, the 31-year-old pregnant Duchess will listen to the tunes of Bruno Mars and Calvin Harris when her little one arrives. The publication reported that music has helped her with her fears about giving birth. 

"Kate says she's never been so nervous and feels physically sick about giving birth," a source said.

The source added that Middleton is still worried that Prince William might not make it back from his duties as a RAF pilot for the birth of the baby. 

"To make matters worse, Prince William is still working and isn't around to comfort her. She's a real mess," the source said. "He's expecting a phone call and a frantic dash from work when Kate goes into labour. He knows Kate's having a tough time right now and hates not being there to support her," the source added. 

William is scheduled to take paternity leave when the baby arrives, it is not indicated if he is allowed days off before the baby is expected to come.

"William is expected to take two weeks off. This is extra time in addition to his holiday entitlement. If he wants to add holiday to extend his paternity leave he must get permission from senior officers," a source said. "At this stage it seems he is going to return to work within a fortnight of becoming a dad."

Despite the new claims, it was revealed Thursday that Middleton is excited for the pregnancy and can't wait for the baby to arrive. 

Kate finds pregnancy fascinating," the source told Us Weekly. "[She's] really enjoying her final weeks of pregnancy.

The source added that William is excited too, saying, "They're both so excited and have so many questions... they want to know what the baby will look like and who it will take after."
