Peep Show star Big Suze has joined senior royals for vigil at Queen's coffin at Westminster Hall.
Actress Sophie Winkleman has also appeared in Two and a Half Men, Death in Paradise and Trust and Sanditon.
Lady Frederick Windsor was among the special royal guests at the service in London tonight.
The star is married to Lord Frederick Windsor, whose father is the Queen's cousin Prince Michael of Kent, and she is also a half-sister of Strictly Come Dancing host Claudia Winkleman.
Sophie, an actress who also more recently appeared in This Is Going To Hurt, married Lord Freddie, a financial analyst in 2009. They have two children - eight-year-old Maud and six-year-old Isabella.
She is the half-sister of Strictly Come Dancing host Claudia Winkleman.
She shares a special connection with Prince Harry and Meghan Markle's daughter Lilibet - as she too was born in the US.
Prince Andrew was wearing military uniform tonight as he takes part in the solemn vigil with King Charles.
The new sovereign gave his younger brother special permission to don Navy garb as Her Majesty lies in state ahead of Monday's funeral.
Andrew, 62, was also joined by siblings Princess Anne and Prince Edward for the sombre event at Westminster Hall as members of the public continued to quietly file past.
At this evening's emotional Vigil of the Princes, the King was also accompanied by Camilla, Queen Consort.
Members of the royal family including James, Viscount Severn, Lady Louise Windsor, the Countess of Wessex, Jack Brooksbank, Zara Tindall, Mike Tindall, the Duke of Kent, Mia and Lena Tindall, the Duchess of Gloucester, and the Earl and Countess of St Andrews were also in attendance.
So too were Princess Eugenie, Princess Beatrice and her husband Edoardo Mapelli Mozzi.
Spouses of the senior royals and other family members were seen standing at the back of the hall and not by the coffin.
On Monday, Westminster Abbey is expected to be filled with over 2,000 guests for the Queen's funeral.
The cortege will then leave London for Windsor Castle and a committal service will take place at St George’s Chapel at 4pm on Monday.
Some 800 people, including members of the Queen’s Household and Windsor estate staff, will attend the committal service.
The Queen will later be buried with the Duke of Edinburgh in King George VI’s chapel in Windsor Castle in a private service at 7.30pm the same day.
The burial service conducted by the Dean of Windsor and attended by the King and royals will remain entirely private, as a “deeply personal family occasion”.
