Princess Tessy of Luxembourg announced she is divorcing her husband Prince Louis on their wedding day in 2006
The marriage of Prince Louis and Princess Tessy of Luxembourg has ended in London.
The undefended 'quickie divorce' obtained by Princess Tessy on the grounds of 'unreasonable behaviour' took just a few minutes at the Central Family Court today.
The couple, who live in London, were not present when they were granted a decree nisi by District Judge Richard Robinson.
Their marriage was solemnised at the Grand Ducal Palace in Luxembourg in September 2006 and they have two sons, Prince Gabriel, 10, and Prince Noah, nine.
Among the court papers made public was a sworn statement signed by 31-year-old Princess Tessy in January which said that 30-year-old Prince Louis's behaviour, as set out in her petition, was continuing.
The paperwork stated that a judge found that Princess Tessy was 'entitled to a decree of divorce, the marriage having irretrievably broken down, the facts found proved being the respondent's unreasonable behaviour'.
The former couple are seen with their sons at the baptism of Princess Amalia of Luxembourg in the summer of 2014
Prince Louis, one of the duke and duchess' five children, reportedly met Tessy during a visit to the Army, which she joined aged 18. Pictured, the couple in September 2013

Details of the unreasonable behaviour were not given.
The couple's case was fourth in a list of six before the judge, appearing as 'Princess of Luxembourg H R H T v Prince of Luxembourg H R H L X'.
Court papers gave their full titles as Her Royal Highness, Princess Tessy of Luxembourg, Princess of Nassau and Princess of Bourbon-Parma and His Royal Highness, Prince Louis Xavier Marie Guillaume of Luxembourg, Prince of Nassau and Prince of Bourbon-Parma.
Prince Louis, who works in the field of social corporate responsibilities, is the third son of the Grand Duke Henri and Grand Duchess Maria Teresa of Luxembourg.
The couple were reported to have met for the first time while Prince Louis was visiting the Luxembourg Army where his future wife served as a corporal, taking part in the 2004 United Nations peace-keeping mission in Kosovo.

Upon their marriage Prince Louis, aged 20 at the time, had to give up his succession rights as his bride, then aged 21, was not of royal blood.
Although he retained the title of Prince of Luxembourg, his wife and sons were originally given the surname Nassau and no titles.
This changed on Luxembourg National Day on 23 June 2009, when Tessy was given the title Princess of Luxembourg and their sons and future heirs the title, Prince of Nassau.
The divorce will not be made final until an application is made for the decree absolute, which can be done in six weeks.
Princess Tessy released a statement in January confirming their 'extremely sad' divorce but said they will 'always remain unified by parenthood to our two precious boys'.
She said: 'I am very sad to confirm that Louis and I are getting divorced after 12 years together.

In January, Princess Tessy published a statement which said: 'I am very sad to confirm that Louis and I are getting divorced after 12 years together'
'Despite our separation, we will always remain unified by parenthood to our two precious boys.
'It is extremely sad for both of us to realise that we will walk separate life paths from now on.
'In these challenging times, I ask for privacy for both of us and especially the privacy of our children to be respected. No further comment will be given at this stage.'
The most recent high-profile royal separation was between Princess Martha Louise of Norway and her husband Ari Behn, who announced they were divorcing in August last year.
Prior to that, Princess Alexandra of Denmark and Prince Joachim officially ended their marriage in 2005.
