Amy Winehouse reportedly 'insulted' the King of the Zulu Nation

The singer and her director boyfriend Reg Traviss were at the opening of new African-themed restaurant Shaka Zulu in Camden, north London, which included a speech by monarch Goodwill Zwelithini on Wednesday night (06.08.10).

Amy is said to have arrived late and drunk and then proceeded to fall asleep during the king's 15-minute address to the 200 guests.

A source told The Sun newspaper: "It was embarrassing, Amy was in a state. People were cringing. Before the king arrived she was downing glasses of wine and kissing Reg. She completely insulted the king during the speech and showed no respect."

Reg tried his best to keep his girlfriend under control and didn't leave her side.

At 9pm he left with Amy via the backdoor and put her in a taxi home.

The 'Rehab' singer's antics follow her going on a huge bar crawl around London earlier in the week which ended in her falling asleep at a table outside a pub owned by Reg's parents.

During the night she was seen drinking with former 'O.C.' actress Mischa Barton in Camden pub The Hawley Arms.
