"Family Day" is supposed to be a day of happiness, support and celebration of progress in sobriety on 'Celebrity Rehab with Dr. Drew' (Sun., 9PM ET on VH1). But things quickly spiraled out of control when Jeremy Jackson's sister made a joke in very poor taste.

Jackson has become good friends with Amy Fisher in rehab, but his sister didn't make the connection when she first met Fisher, "because you didn't introduce yourself as 'Buttafuoco face shooter."

Now, that's a very harsh thing to say to someone. She has no way of knowing how Fisher is tortured emotionally about what she did, though the fact that she's in rehab says quite a lot about how she's coping with something.

Jeremy Jackson isn't your usual candidate for 'Celebrity Rehab.' He spoke Wednesday on 'Access Hollywood Live' (weekdays, syndicated on NBC) about taking multiple controlled substances, but rather than the more popular "party drugs," the former 'Baywatch' star had problems with steroids and human growth hormones.

Jackson is seen in a clip revealing a laundry list of substances to Dr. Drew Pinsky, the main counselor on 'Celebrity Rehab.' Jackson noted that keeping in shape without the substances has been a challenge. "It's a trade-off," he said. "I'm 188 pounds. When I went on the show, I was a little over 200 pounds. So I've lost at least 15 pounds, some of it muscle."

Jackson said he's lost muscle and gained fat, which he called a "bummer." No more so, we're guessing, than going on 'Celebrity Rehab.'

When the new season of 'Celebrity Rehab with Dr. Drew' premieres on Sun., June 26 at 9PM on VH1, expect to see lots of familiar reality TV faces.

Dr. Drew's new patients include tabloid mainstay Michael Lohan, Bai Ling and 'Baywatch' star Jeremy Jackson.

Besides the celebrity patients, Dr. Drew will be joined by returning counselor Bob Forrest and resident technician Shelly Spraguem, along with depression and bipolar disorder expert Dr. John R. Sharp, M.D. and 'Sober House' house manager Jennifer Gimenez as resident technician.

Meet the rest of the cast below.

Shooting started Wednesday on the new season of 'Celebrity Rehab With Dr. Drew' and reports from the set suggest Dr. Drew will have his hands full with the new cast. According to reports, there's a Lohan, a 'Baywatch' star, a former New York baseball great, and at least two 'Real Housewives.'

The show has apparently been after Lindsay Lohan for years without success. However, producers have reportedly nabbed her father and are hoping that Lindsay and/or her mom Dina will appear on the show for some "family counseling."

According to RadarOnline.com Michael Lohan has checked into 'Celebrity Rehab' to deal with his anger management issues, not drugs- or alcohol-related problems.

So what's Jeremy Jackson been up to?

Jackson played David Hasselhoff's son Hobie on Baywatch many moons ago, and he's now one of the cast members of VH1's new celebreality (gah) show Confessions of a Teen Idol. He'll be joined by former Real World star Eric Nies; Christopher Atkins, the star of The Blue Lagoon; and former Beverly Hills, 90210 star Jamie Walters. Which makes me think that maybe the title of this show should be Confessions of a Former Teen Idol, since all of these guys are in their late 20 or 30s or 40s.

Actually, without even watching this show I can tell you what these people are up to: they're starring in a new VH1 reality show. They're trying to get back into the business in a big way, and I guess these days that means first starring in a reality show. Which, by the way, starts on January 4.
