Artie Lange tweeted a cautionary tale on Christmas Day.

The comedian, 51, took to Twitter on Tuesday with a photo of his collapsed nose.

“This is it but I believe her nose had a septum and had not been hideously deformed due to over 3 decades of drug abuse,” he wrote.

Earlier this month, Lange tested positive for cocaine while serving four years’ probation for heroin possession. He was spared a jail sentence for violating probation.

When the court received the results of the drug test, the comedian — who has been extremely open about his past drug use — didn’t deny that he did cocaine.

“I wouldn’t be arrogant enough to come in here after using cocaine for two days,” he said during the New Jersey hearing. “It’s in my system and it shouldn’t be.”

A rep for Lang did not immediately respond to a request for comment.
