New Love Island arrival Kate Lawler burst into tears after offending Calum Best.

The Big Brother 3 winner jokingly accused him of stealing one of Brendan's beers, in reference to her decision during the Ask Kate task that he is the biggest drinker.

"Don't point the finger at me again," Calum told her. "Who do you think you are? It annoyed me that you accused me of taking someone's beer. Think about what you're saying."

"I don't need to think about what I said, when Brendan asked who was the biggest drinker I said probably Lee or Calum," Kate replied. "So I said it was probably Lee or Calum who took your beer."

"Look, it's not a big deal," he said. "I don't mind being called a big drinker, I like a drink, I just don't like that you said I nicked his beer."

Later, Lee explained to Kate that jokes about alcohol could be a "sore point" for Calum.

"If that was me that had lost my dad and someone made a joke - it must have looked so bad," Kate realised as she started to cry. "I'm so thick, I didn't understand."
