Kate Middleton is to attend a public event next month that's expected to be one of her last before she gives birth to her second child with Prince William. But she will not be making the outing alone. Despite rumors she is involved in another "war" with Queen Elizabeth II, the Duchess of Cambridge is scheduled to accompany Her Majesty to said event. 

Kate, 33, and Queen Elizabeth, 88, will both attend the annual Commonwealth Day service at Westminster Abbey on March 9, Hello magazine reports. Kensington Palace has confirmed that Prince William, 32, as well as the queen’s husband, Prince Philip, her son, Prince Charles, and daughter-in-law, Camilla, the Duchess of Cornwall, will also be present.

This year, the theme of the queen’s Commonwealth Day message will be “A Young Commonwealth." Her presentation will be followed by an hourlong service, which will include the singing of hymns and a reading of testimonies. Afterward, the royal family will be presented with flowers from children attending the event and will walk to the Commonwealth Flags.

Let’s hope for the sake of the ceremony and Kate -- who is due to give birth in April -- that she and the queen will be able to put their rumored differences aside for the occasion. According to a report from the March 9 edition of Life & Style, the duchess recently engaged in an argument with the queen over a difference of opinion regarding child-rearing. The latest allegations come on the heels of several reports that the two have a tumultuous relationship, specifically in regards to the raising of Kate and William's 1-year-old son, Prince George.

According to the magazine, Kate “walked out” on the queen during a recent visit to her Sandringham estate when they disagreed over how she should raise her new baby. While the duchess reportedly wants to move in with her mother, Carole Middleton, following her child's arrival, the queen is said to be determined that Kate will hire a baby nurse. “The queen raised her voice as she clashed with Kate and Prince William about how they raised their child,” a “royal insider” told the magazine. “Kate couldn’t bear it any longer and walked out."

Despite the queen’s alleged demands for Kate to hire outside help, Kate is said to be intent on raising her children how she sees fit. “Kate wants to do things her own way and wants the queen to stay out of her baby’s life, and the queen is furious,” an insider told the magazine. “She’s sticking to her guns about the new baby. She knows just how she wants to raise the child and won’t let anyone interfere, especially not the queen."
