Queen Elizabeth II will be supporting Kate Middleton next week for her big event. The Duchess of Cambridge will have her moment at the Chelsea Flower Show, wherein she designed a garden, and it will be showcased this coming Monday.

Hello! Magazine reported Her Majesty would be attending the event to support the big reveal of her granddaughter-in-law. The Queen will reportedly be present during the first day of the annual flower show, and other royal family members will be there as well.

The report says Queen Elizabeth will be viewing the RHS Back to Nature Garden that Middleton's co-designed with the Royal Horticultural Society and award-winning landscape architects Adam White and Andrée Davies. News about Middleton's involvement with the Chelsea Flower Show was first reported back in February.

The trio's work is reportedly designed to suit all ages, and in fact, it has child-friendly touches which include a tree house and a stream. Also, it also features a campfire, a swing seat, as well as a rustic den that looks similar to what Prince George, Princess Charlotte and Prince Louis use in the grounds of Anmer Hall.

Meanwhile, Meghan Markle is reportedly designing a garden for charity Camfed as well, which will feature a breeze-block school house surrounded by crops such as okra and peanuts. However, according to an insider, the Kensington Palace reportedly intervened so that they could stop Prince Harry and Markle from colliding with Middleton's pride and joy.

Queen Elizabeth and the Duchess of Cambridge reportedly have a very close relationship, even though they aren't usually seen together in public. But earlier this year, the royal ladies made their first joint outing after seven years. They reportedly arrived in the same vehicle, and they were even seen sharing the same blanket.

Her Majesty and Middleton were first seen together in a joint engagement back in 2012, along with Prince William. During those times, the two women were spotted chatting politely, and they were also photographed laughing as the Queen seemed to crack a joke. Based on the photos over the past years, Queen Elizabeth and the Duchess has become allies, and the latter is reportedly confident whenever she speaks with the monarch.

Also, the Queen is said to be "very fond" of Middleton's values. Particularly, Her Majesty likes the Duchess of Cambridge's "middle-class values," and she also likes how close she is to her family. Just like her granddaughter-in-law, Queen Elizabeth is reportedly dedicated to her family as well.
