Australian Prime Minister Scott Morrison and wife Jenny have arrived at the White House for an official state dinner in the Rose Garden. The couple were greeted by host U.S. President Donald Trump and First Lady Melania. A stunning Mrs Morrison shone in a sparkly navy halter neck gown from Australian designer Carla Zampatti with her hair pinned up in a chic updo while Melania opted for a frilly light green frock. While Mr Morrison and Mr Trump appear to be enjoying a ‘bromance’ , things appeared somewhat frostier between their wives. There was an awkward exchange between the two women, who appeared unsure of whether to shake hands or hug before they settled on a kiss on each cheek. The pair earlier also looked a little uncomfortable as they stood next to each other for a photo and exchanged greetings. more videos 1 2 3 Watch video Kathy Griffin films Getty fire raging from her driveway Watch video Trump tells police chief conference Baghdadi ‘didn’t die bravely’ Watch video Veteran rescues a dog in Afghanistan after the two become friends Watch video President Trump attends World Series game at Nationals Park Watch video Boris Johnson doesn’t secure his majority…
