Mischa Barton Upsets Amy Winehouse During Pub Row

Amy Winehouse and Mischa Barton were involved in a row at a pub in London on Monday (August 2), it's been reported.

The pair are understood to have fallen out after the actress tried to take a drink out of Winehoue's hand.

A source told The Sun that Barton also told the singer, who was later pictured slumped on a bench, she had drunk “enough for the night”.

“She wasn't being a killjoy,” the source said of Baron's actions. “Amy looked upset. 

"Obviously she was drunk and didn't take it well, she yelled at Mischa that it was none of her business and her mate told her to leave it."

Barton was later photographed leaving the Hawley Arms early in the evening - see photos below.

As previously reported on Gigwise, Winehouse is understood to have gone on to have a 16-hour drinks bender after falling out with her new boyfriend.

The singer, who has battled drink and drug problems, was pictured on Tuesday morning (August 3) reclining on a bench.
