Prince William will not be carrying a phone for a couple of hours on Saturday, the day his wife, Kate Middleton, is expected to go into labor to give birth to the couple's second child. The prince is expected to be in central London at the Cenotaph with Queen Elizabeth and the Duke of Edinburgh to attend a ceremony marking the 100-year anniversary of the Gallipoli campaign in World War I.

However, William’s aides are expected to inform him the minute Kate goes into labor, Vanity Fair reported. The magazine also reported that Kate, the Duchess of Cambridge, is also not expected to step out of the Kensington Palace until she has her second child.

“She won’t go out because she is determined not to be seen in public,” a source told Royal Watch, adding: “She wants the next time she is seen in public to be with her new baby.”

Two rooms have been reserved for Kate at the Lindo Wing of St. Mary’s Hospital in London where she is expected to give birth. This was the same wing where Princess Diana had given birth to Prince William.

Kate’s mother Carole Middleton was also spotted on Friday as she stopped by London’s Richard Ward salon, ahead of her daughter's labor and reportedly looked very happy. Carole is reportedly staying at the Kensington Palace with William and Kate.

“She (Carole) was very happy and smiley," an onlooker told the Us Weekly, adding that Carole seemed "very friendly and close" with Ward. Carole reportedly got a haircut and blow-dry at the salon and is expected to face the media soon after her daughter gives birth to the child.

Fans also reportedly started lining up outside St. Mary’s Hospital’s Lindo Wing to catch a glimpse of Kate and her newborn.
