Celeb dad Michael Lohan, batshit crazy actress Sean Young, former baseball player Dwight Gooden, Long Island Lolita Amy Fisher, rocker Steven Adler (he’s back!), actress Bai Ling, “Survivor” contestant Jessica “Sugar” Kiper and “Baywatch” star Jeremy Jackson.

Not so much of a “celebrity” lineup, is it?

Will you tune in for Celebrity Rehab season 5? It premieres on Sunday, June 26.

Jeff Conaway, best known for his roles on “Taxi,” “Babylon 5″ and in “Grease,” had a very public struggle with drugs and addiction, even appearing on Celebrity Rehab.

RadarOnline says Conaway’s death is the end to “a long, sad road of addiction that made him one of Hollywood’s cautionary tales.”

Jeff Conaway had been in the hospital since May 11, with reports yesterday that he had no brain activity.

While initial reports were that Conaway was in the hospital for a drug overdose, Dr. Drew Pinsky said Jeff had pneumonia and sepsis, a blood infection.

I had always hoped this guy would get it together.

RIP, Jeff.

Michaele Salahi’s husband plans to sue Celebrity Rehab, saying that the reality series illegally fired Michaele because of a health condition.

Tareq Salahi issued the following statement: “[Michaele] was fired due to her health condition which is a violation of the Americans with Disabilities Act.”

Michaele has said before that she suffers from multiple sclerosis.

Remember when Michaele Salahi said Whoopi Goldberg hit her on The View (video)? Yeah, Salahi likes to stir the pot, no doubt.

Mike Starr appeared on TV’s Celebrity Rehab during season 3, but was arrested just weeks ago for drug possession.

Mike Starr’s former bandmates, Jerry Cantrell and Sean Kinney, released the following statement about Starr’s death: “Jerry and Sean are mourning the loss of their friend and ask that the media respect their privacy – and the privacy of Mike’s family – during this difficult time. Their thoughts & prayers are with Mike’s family.”

Celebrity Rehab host Dr. Drew Pinsky responded to news that Mike Starr was dead, posting the following on Twitter: “Devastating to hear of Mike Starr succumbing to his illness. So very sad. Our prayers are with his family.”

In this Today show video clip, Rachel Uchitel (with Dr. Drew by her side, naturally) tells about her “love addiction.”

Eric Roberts – brother of Julia Roberts and dad to Emma Roberts – has been battling cocaine addiction for some time.

Eric Roberts will be rooming with Jeremy London on Celebrity Rehab. London says of the room assignment, “Eric Roberts is my roommate and is simply amazing. He’s an incredible person. Dr. Drew rocks and there is real healing here.”

Celebrity Rehab airs in October.

London’s wife was getting treatment at Dr. Drew Pinsky’s Pasadena Recovery Center for prescription pill addiction when she became ill. After Jeremy checked in for Celebrity Rehab, “Melissa suffered the brain hemorrhage and was immediately taken to the hospital,” a source tells the site.

She has since been released from the hospital and returned to rehab.

Melissa reportedly was having a difficult time with withdrawal.

London made news last month when he said he was kidnapped and forced to take drugs at gun point. That’s one humdinger of a story, right?

London addressed his crazy-ass story with People, saying, “If I heard someone saying this, I would probably doubt it as well. I was acting my way through the whole thing, telling myself, ‘Just play like you are one of them.’”

Jeremy London checks into the Celebrity Rehab facility this weekend, joining Tila Tequila, Jason Wheeler and Shauna Sand.

Will you be watching London on Celebrity Rehab?

Bret Michaels’ doctor, Dr. Joseph Zabramski, told reporters at the press conference: “Mr. Michaels was indeed a lucky person, a very lucky person.”

Michaels was discharged from the hospital, less than two weeks after he suffered a brain hemorrhage.

Dr. Zabramski noted: “He’s improving and I expect him to continue to improve. I really expect that he will fortunately make a 100 percent recovery. He’s just one of those lucky people – 10 to 20 percent who make a complete recovery and can resume all of their normal activities.”

Amazing.

But is the Mindy McCready sex tape approved by the singer? Vivid Entertainment set an April 19 release date for the sex tape and no lawsuit has been filed by McCready.

Also, McCready apparently provides narration during the video about her affairs with Alan Jackson, Dean Cain and Roger Clemens.

Sounds like she’s fully on board and collecting a paycheck off of the sex tape.
