Lady Gaga left The Ecuadorian Embassy at midnight looking like a witch, having spent five hours inside visiting Wikileak's founder Julian Assange. Gaga made no comment as she left the premises.

The visit came as a court ordered supporters and friends of the 41-year-old Wikileaks founder hand over $150,000 they had offered as surety for his bail which he jumped when he sought asylum in the embassy.

The singer, who puked on stage the day before in Spain, arrived at the embassy and shared dinner with the Australian activist in his backroom of the embassy in the upmarket Knightsbridge in central London.

Dressed in black and wearing a witches hat, she posed with a beaming Assange - despite him exhibiting a stain on his t-shirt - with the images posted immediately on the web.
