LOS ANGELES • Hollywood star Leonardo DiCaprio has turned over a Best Actor Oscar won by Marlon Brando.

But will Australian supermodel Miranda Kerr have to fork over her diamonds?

The items are reportedly gifts from Malaysian businessman Jho Low, whom the United States authorities have cited as being involved in a money-laundering scheme linked to a Malaysian sovereign wealth fund.

The US Department of Justice is attempting to recover some assets which were bought with the diverted funds.

W magazine reported that Mr Low showered Kerr with jewellery over the course of their year-long relationship, after she and actor Orlando Bloom divorced in 2013.

Kerr recently married Snapchat chief executive Evan Spiegel.

DiCaprio's spokesman said the actor contacted the Justice Department in July last year after learning of a civil action against "certain parties involved in the making of The Wolf Of Wall Street", a 2013 movie in which he starred.

He offered to surrender to the US authorities any gifts "from the parties named in the civil complaint", reported Agence France-Presse.

"He has also returned an Oscar won by Marlon Brando, which was given to DiCaprio as a set gift by (the producers) to thank him for his work on The Wolf Of Wall Street," the spokesman added.

But how did Brando's Oscar for the 1954 movie On The Waterfront end up in others' hands?

The Independent reported that the actor's estate executor had said that the statuette went missing while he was still alive.

Brando died in 2004.

"He was trying to track it down and kept hitting dead ends," she said, adding: "It would be great to get it back."
