Australia has gone One Direction crazy so we thought we'd devote an entire episode of Week in Tweets to the boys.
• Zayn (@zaynmalik) got his shirt off and doesn't seem to be loving Australia as much as we'd like.
• Harry (@harry_styles) has been learning some Australian slang.
• We check out some slightly inappropriate 1D fan tweets from super fans.
• Vegemite is trending because Niall had a taste and hated it, so Dave tries it too.
