UPDATE: Leakes debunked a report that alleged she suffered a heart attack on her official website on Tuesday. After thanking everyone for their "concerns and prayers" she shared her medical diagnosis.

"Late last week I wasn't feeling well and was feeling a little short of breath. I know my body and I know when I should be concerned so I went to the hospital to get checked out. After some routine tests I was diagnosed with blood clots in my lung. I'm told this happened to me because of the constant traveling around the country that I do for my job," she wrote. "Contrary to published reports I did not have a heart attack."

Leakes' fellow reality star and friend who attended her June 22 Atlanta wedding, Millionaire Matchmaker star Patti Stanger sent her well wishes on the social media site.

"Feel better baby @NeNeLeakes I can't loose my gurl we gotta a lot of plans coming up. If u need me I'm here," she wrote.
