Donald Trump Jr's wife Vanessa files for divorce.

Donald Trump Jr. and his wife, Vanessa Trump, may be getting divorced.

Vanessa Trump, a former model, is seeking an uncontested divorce from the president’s son, according to a public court record filed Thursday.

Details of the divorce complaint haven’t been made public.

The couple, both 40 years old, married in 2005 and have five children.

The Trump Organisation, where Donald Trump Jr. is an executive, didn’t immediately respond to an emailed request for comment.

The court filing didn’t include the names of the couple’s lawyers.

Vanessa Trump’s engagement and marriage to Donald Trump Jr. had been a subject of tabloid fascination in New York long before her father-in-law, Donald Trump, entered politics.

At the time of their engagement, there were unflattering stories about how Trump Jr. had accepted a free diamond ring from a jewellery merchant in New Jersey in exchange for staging a recreation of his wedding proposal outside the store for reporters and TV cameras.

Last month, Vanessa Trump opened a letter to her husband containing an unidentified white powder and was briefly hospitalised as a precaution, but the substance turned out to be non hazardous.

A Massachusetts man later was charged with sending the threatening letter.
