Chris Brown was over-tired and suffering from dehydration when he fell sick at a recording studio in the early hours of Friday (09Aug13), according to a U.S. report. Rumours suggested the singer had suffered a frightening health scare after paramedics were called to Los Angeles' Record Plant studios, but new details have emerged alleging the star was feeling the strain of a long day at work and staff mistook the symptoms. A source tells Hollywoodlife.com, "It wasn't a seizure. He just felt light headed and dehydrated and fell on the ground. It scared us, but in seconds he was talking, saying he was all right. When we saw him falling, we didn't know what was up so we called 911... He's cool, but he is stressed and didn't have a good week. He was in the studio for a lot of hours with like no sleep at all and a lot on his mind and whatnot. He just overdid it but now he's doing all right and will be out this weekend like always." Brown is said to have refused treatment from emergency workers and did not want to be transported to a local hospital for a check-up.
