Howard Stern's former sidekick, Artie Lange, just went on this epic rant on social media — and fans are worried the troubled comic may have relapsed, Breaking Celebrity News has learned.

Lange posted a series of bizarre and random tweets following a tweet by Barack Obama discussing support for several upcoming democratic candidates.

Among the tweets, the troubled comedian suggested that the former president engage in several sex acts with the Jenner family, including an alleged Bill O' Reilly accuser.

"F**k Kylie & Kendall and make Caitlyn Jenner watch," another tweet said.

The comedian then made a reference to his book sales slamming Obama for having a lower book rating.

"If ur not responding cuz of personal s**t let’s get it out man. The week my first book came out it was number 1. Yours was 8. Sorry. Peace. Dedicate the next book to the only 2 ladies u haven’t O Banged! Then put the names of ur two daughters. I forgot! They’ll be honored!"

Before signing off he asked Obama to die the same way Leondaro DiCaprio's character died in Titanic.

"That should be how u die but it’s not water. It’s p**sy," Lange wrote.

"I gotta go but listen. If u want me to do this w you u should know it has to be entirely in Jersey. I’m on Probation. Can’t really travel. But I hear if u give an ex President the best idea ever he can make a few calls! Hahahaha."

Fans then responded for those closest to the comedian to check on his well being.

In June, Lange was sentenced to four years probation and ordered to attend an outpatient rehab program following his drug possession charges.

The judge in his case cautioned the 50-year-old to stay sober or he would face the slammer.

“You pose the biggest risk to yourself,” the judge told Lange after his sentencing. “One of your doctors said that if you relapse again, you’re basically going to kill yourself.”

“I hope you take this sentence seriously and do what you need to do — not only for you but for your family, who depend upon you,” she said. “This is your one chance.”

Lange has long struggled with drug addiction and relapsed several times. This past year alone Lange said he almost died after collapsing during a gig
