Bobby Brown is just FLAT UP CRAZY!

Brown's attorney announced earlier this week that he had suffered a mild heart attack.  Now, Bobby says it never happened.

"None of it’s true," Brown said. "I went in for a checkup. The doc gave me a clean bill of health."

Phaedra Parks, Brown's attorney, announced on Wednesday that the singer was taken to two hospitals on Tuesday night.

"This morning they did diagnose him as suffering from a mild heart attack ... they attributed to stress and diet," Parks said, noting that she had spoken with him.

Brown, who is scheduled to perform Saturday in Los Angeles, said that the reports about him having a heart attack gave him a "jolt" and that he felt he had to speak out.
