Bride-to-be Meghan Markle is having her hen do at a mystery five-star resort today - but two important people won't be there.

The Suits star, 36, will be celebrating her upcoming nuptials with her close friends, but the location is being kept a closely-guarded for security reasons, reports the Daily Mail.

Luxury Oxfordshire resort Soho Farmhouse has been widely tipped as Meghan's party location of choice after her and rumoured bridesmaid Millie Mackintosh were pictured there together last year.

Soho Farmhouse refused to comment on whether the hen party is being held there when approached by MailOnline.

Her mother Doria Radlan, 61, isn't going to be there and will be staying at home in Los Angeles, reports The Sun.

Also missing out will be her sister-in-law-to-be the Duchess of Cambridge, 36, who is heavily pregnant with her third child.

After speculation she could be her bridesmaid, Made in Chelsea's Millie Mackintosh is likely to be among today's hen party guests.

She has become close friends with the new Royal after she moved from Toronto to the UK.

Also likely to be in attendance is her fashion designer friend Misha Nonoo and friend of fiance Violet von Westenholz.

Wimbledon champion Serena Williams is another likely "hen" after the two met at a charity football match in 2014 and hit it off immediately.

Canadian stylist Jessica Mulroney could also be going today, counting herself as one of Meghan's best friends.

Suits co-star Abigail Spencer is another member of Meghan's inner circle and could well be preparing herself for a day of hen party pampering today.

Friends Amanda Schull and Lindsay Roth could also be on the list.

Princesses Beatrice and Eugenie along with little Princess Charlotte could be there too.

Miss Markle previously joked she would be having her hen party in Cardiff after she visited the Welsh capital with Prince Harry.

Llandaff sisters Anne and Judy Daley told Meghan they would be more than welcome, to which she replied: "I bet that would be a lot of fun."

The pair even bought her a plastic tiara and a bridal sash as a gift.

A Clarence House spokesman refused to comment when approached by MailOnline.
