Kate Middleton's due date is still a mystery after reports indicated that she may give birth during the week of the 4th of July holiday.

According to E! News, media outlets have already started lining up outside St. Mary's hospital, where the pregnant Duchess will give birth to her first child with husband, Prince William.

The British media are ensuring they capture every moment of Middleton's royal baby delivery, after several news outlets reported that she could give birth 10 days earlier than her due date, said to be approximately around July 13-14.

The Telegraph reported that there is a huge possibility the 31-year-old Middleton could go into labor sometime this week, around July 3-4, following in the footsteps of Princess Diana, who fooledd the media by claiming William, 31, was due on her birthday, July 1, but he arrived 10 days earlier on June 21, 1982.

William and Prince Harry were both born at St. Mary's hospital.

Middleton is expected to be in the Lindo Wing of the hospital. The wing offers a hotel service team, which will reportedly cater to Middleton's dietary needs. 

The Duchess and Prince William have yet to discover the sex of their first child.

Middleton is planning to go through a natural labour delivery when she gives birth. 

Enstars reported earlier that Middleton will have a musical playlist on deck when she gives birth, which will include tunes from Calvin Harris and Bruno Mars. OK! magazine noted that the musical selection has reportedly helped with her fears about the delivery of her first child. 

"Kate says she's never been so nervous and feels physically sick about giving birth," a source said. "To make matters worse, Prince William is still working and isn't around to comfort her. She's a real mess."
