Princess Eugenie has already started picking her entourage for her royal wedding.

According to Joseph Carey, a journalist for Express, the next royal bride's entourage will include Princess Charlotte and Theodora Rose, the daughter of Robbie Williams, as her flower girls. Prince George is also expected to be the pageboy.

Royal commentator James Brookes said earlier that Princess Eugenie and Jack Brooksbank would likely opt for children for their entourage. This is to ensure that the bride would not be overshadowed by her celebrity friends during her wedding.

"I think the couple will rule out having older adults playing a big part in the ceremony, not least because it's royal tradition, but also because of the celebrity nature of their friendship circle," Brookes said.

"When you're close friends with the likes of Ellie Goulding and Cara Delevingne as Eugenie is, there's the risk of being overshadowed. And Eugenie will, like any bride, want to be the centre of attention on her big day!" he continued.

As for Princess Eugenie's maid of honor, many believe that she will give the role to her sister, Princess Beatrice, considering their close sibling relationship. "I think it's extremely likely we'll see her older sister Beatrice play a big part in the day, most likely as Eugenie's maid of honour," Brookes said earlier. "The sisters are extremely close, get on well and Eugenie's said in the past that family means a great deal to her."

Princess Eugenie previously opened up about her relationship with Princess Beatrice in a past interview. She revealed that while they agree on a number of things, they also think differently.

"We get on fantastically well, perhaps because we do and think different things. I am definitely not as polite as Beatrice, I have to say. I tell it as it is. I am shyer at first," Princess Eugenie told The Telegraph. "Like, at a party I will say to Beatrice as we go in, 'Oh, you go first.' But then, when we're actually in, I am much louder and she is far more polite and solicitous."

Princess Eugenie and Brooksbank will be tying the knot on Oct. 12 at St. George’s Chapel in Windsor Castle.
