is on the mend.

The Biggest Loser host confirmed reports that he had suffered a heart attack with an Instagram post on Monday, sharing a photo of himself sitting up in a hospital bed and holding his beloved dog, Karl.

"Two weeks ago yesterday I had a heart attack," he wrote. "I am feeling better. Just taking it easy. KARL has been a great nurse."

The 51-year-old didn't offer much information about what led to the heart attack, but did indicate that he's recovering at home.

"I want to thank everyone for the outpouring of message and support," he continued. "It feels good to be cared about. I've been home for eight days now. Again, THANK YOU SO MUCH!! I'm lucky to have such good friends and family to take care of me right now."

TMZ first reported the news, claiming that the health scare left Harper unconscious for two days after collapsing in a New York City gym.
