An insider told E! News that Kanye "didn't have a major health scare or seizure. He just suffered a migraine and went to hospital simply as a precaution." According to local reports, he also underwent an MRI scan.
Thankfully, the 37-year-old made a quick recovery - hours later was back on stage for his final performance in Melbourne.
Kanye touched down in Australia last week with his wife Kim Kardashian and their daughter North West.
They are now in Sydney on the next leg of the singer's multi-date Yeezus tour – Kim also has work commitments in the city, promoting her new clothing line, Kardashian Kollection.
