Kate Middleston's younger sister Pippa has settled on the date and place of her own nuptials with financier boyfriend James Matthews. In addition to this big news, Princess Charlotte and Prince George are confirmed to have starring roles on the upcoming wedding.

According to the reports, Pippa Middleton and James Matthews will marry on May 20, 2017 at the Anglican St. Mark's Church Englefield in Berkshire.

The British tabloids, especially the Daily Mail, have been reporting leaks of details about Pippa's nuptials since October, pinpointing a May date, a local church for the venue, and her parents' home in Bucklebury, about 50 miles west of London and seven miles from the church, for the reception.

According to Us Weekly, Kate Middleton will not be a bridesmaid will only most likely read something at the wedding. However, the two royal heirs and Pippa's nephew and niece from Kate will also be expected in the wedding. Prince George, 3, is said to be the page boy, and his sister Princess Charlotte, 1, will be the flower girl.

The bride-to-be was reported to be very hands-on with her wedding. Some sources claim that Pippa prefers a "classic and elegant" wedding and would not want the celebration to be "too expensive or looking gaudy."

Meanwhile, on Pippa Middleton's newly released book "Heartfelt," she shared how she won the heart of millionaire Matthews.

"To win a man's heart is through his stomach." The 33-year-old soon-to-be-wife of Matthews said.

"I am sure he might choose a different dish as his favourite, but it was a very special dinner for us," remembers Middleton. "You roast the Halibut and serve it with lentils. It's delicious. James loves it," according to Brides.com.

To recall, Pippa Middleton and James Matthews confirmed their engagement in July in a statement to Britain's Press Association.
