Kate Middleton is determined not to steal the spotlight when her sister Pippa weds next year.
Pippa, who recently announced her engagement to hedge fund manager James Matthews after less than a year of dating, will walk up the aisle next May and is determined to keep it a "low key" affair.
The Duchess of Cambridge (35) was tipped to act as maid of honour when the party planner weds, but it's now reported that she will play a supporting role in order to avoid taking the limelight away from the bride on her big day.
Pippa is reportedly preparing for an intimate "no frills" wedding with just 150 guests in attendance as they exchange vows at the family's hometown church and a party later at her parents home in Berkshire.
Royal author Judy Wade said she believes Kate will likely perform a reading at her sister's ceremony instead of featuring in the bridal party in order to stick to royal conduct.
"Kate would upstage her sister [if she were maid of honor]. It’s a tricky situation for Pippa. She would want her sister by her side, as who else would she trust to make things go well? . . . But if your sister is a future queen, she is going to upstage the bride and draw attention. Kate would want to be in the background as much as possible," she told People.
Prince George and Princess Charlotte are said to be acting as flowergirl and ringbearer on the day.
Meanwhile, Kate and Pippa's younger brother James said he was "proud" of his sisters, despite the fact it can be difficult to live in their shadow at times - which goes all the way back to their pre-royal lives.
"It’s always been, whether at school or now, that I am Pippa and Catherine’s little brother. It’s probably going to be the story of my life. [But] I am James Middleton. I am very proud to be 'the little brother of…' but, equally, they are proud that I am who I am," he told the Daily Mail.
