Olivia Palermo has got married.

The 28-year-old beauty reportedly secretly tied the knot with German model Johannes Huebl - who she has been in a relationship with since 2008 - at Manhattan's City Hall last Saturday (21.06.14), with just three guests in tow.

The couple had reportedly planned to tie the knot in St. Barts - where Johannes proposed last December - later this year but brought the date forward as the model had been experiencing issues with his visa which may have meant he had to leave the US sooner.

A source told the New York Post newspaper: ''They were planning a big wedding in the fall, but Johannes left Wilhelmina Models last year, and he currently isn't with an agency, and was told he would have to leave the US in September.

''Olivia's friends were surprised when they got married at City Hall on Saturday, with the only guests being his friend Ulli Saeuberlich and her parents, who weren't happy with the rush, but decided to be there at the last minute.''

However, a spokesperson for the former 'City' star insisted they are ''not married yet'', though she did admit they were planning a small ceremony this month ahead of a bigger celebration later.

Barbara Saint-Aime insisted: ''They had always planned to have a small civil wedding in June. The whole visa thing is not relevant. They have been together for six-and-a-half years, they got engaged this past January. They travel so much during the summer, they really don't have much time to plan things. They are not married yet. They are doing a much smaller civil ceremony in the States this month and they are planning to do something much larger later on.''

Olivia previously hinted she planned to marry outside of the US.

She said recently: ''Johannes' friends and family are all over Europe and my parents are happy to travel, so it will probably be somewhere in the middle. Then you will always have a special place in your heart for the destination where you got married.''
