David Beckham accused of writing 'furious' email to his PR about singer Katherine Jenkins' OBE

David Beckham has been accused of writing a 'furious' email to his PR after learning that Katherine Jenkins had been awarded an OBE.

Hackers released several emails said to have been written by the footballer, which include a mention of the classical singer that suggests Beckham was angry to learn she had received an OBE and that he had yet to receive a knighthood from the Queen.

According to The Sun, which cites a number of European media outlets, Beckham sent an email to his longtime PR Simon Oliveira in 2013, which allegedly said: "Katherine Jenkins OBE for what? Singing at the rugby and going to see the troops plus taking coke. F***ing joke."

Jenkins has previously admitted in interviews to taking cocaine when she was younger, saying "curiosity got the better of me".

Oliveira told The Independent that the emails had been "hacked and doctored" from a private account.

"This story is based on outdated material taken out of context from hacked and doctored private emails from a third party server and gives a deliberately inaccurate picture," he said.

"David Beckham and UNICEF have had a powerful partnership in support of children for over 15 years. The David Beckham 7 Fund specifically has raised millions of pounds and helped millions of vulnerable children around the world. David Beckham has given significant time and energy and has made personal financial donations to the 7 Fund and this commitment will continue long term."

The Sun has suggested that the leak threatens to undermine Beckham's charitable work.

UNICEF, a charity which Beckham has been a Goodwill Ambassador for since 2005, has issued a statement supporting him, but a spokesperson also said they were "looking in to" the reports.

"UNICEF has become aware of media reports relating to 7: the David Beckham Fund for UNICEF," the statement read.

"Some reports relate to alleged private correspondence between our ambassador and other parties, which we have not seen and cannot comment upon.

"David Beckham has been a UNICEF Goodwill Ambassador since 2005, and as well as generously giving his time, energy and support to help raise awareness and funds for UNICEF’s work for children, David has given significant funds personally. The 7 fund supports programmes for children, tackling issues such as malnutrition, violence, AIDS and emergencies.

"For example, in June 2016 David visited Swaziland to raise awareness of the devastating drought affecting Eastern and Southern Africa, helping UNICEF reach people around the world with important messages about the need for urgent action."

The statement went onto list some of the work Beckham has done for UNICEF.

The Independent has reached out to representatives for Katherine Jenkins for comment.
