Trump is joined by stunning Melania at pre-inauguration dinner and jokes that if rains today 'people will know it's my real hair'

Donald and Melania Trump attended a black-tie dinner in Washington D.C. on Thursday night, their final engagement before he is sworn in as the 45th president 

Among the many well-heeled guests was Caitlyn Jenner, Jackie Evancho, Wendi Deng and a handful of business titans including members of the Kraft family. 

House Speaker Paul Ryan turned out with his wife Janna and Juanita Broaddrick and Paula Jones, two of a handful of women who have accused Bill Clinton of rape, were also there.  

During his speech, Trump thanked donors and members of his family and celebrated himself as a the hardest working candidate to have ever run for office.

The start of his speech was plagued with microphone difficulties but the president elect's message was not lost in the glitch. 

'That was some big victory, some victory,' he said, thanking supporters and party members who had followed him since the start of his campaign.

Casting his mind back to November's election result, he spoke of the country's changing political map.  

'That was incredible. 'More impressive, there was a map a couple of days after the election, and it showed the red counties and the blue counties. And the entire country, practically, other than the little points, was red,' Trump said.
