Singer Justin Timberlake shocked fans by downing shots of tequila on-stage as he kicked off his first show in Northern Ireland last night.

The SexyBack star also admitted to drinking pints of Guinness before the show, but still managed to wow the 10,000 strong crowd at Belfast's Odyssey Arena with his trademark dance moves.

He told fans, "I've had four or five Guinness before I came on - I love that s**t". I think you all deserve a toast."
