Kelly Clarkson has never been a naturally slim celebrity, and since making her debut and winning American Idol in 2002, her weight has fluctuated as infamously as Oprah Winfrey’s. So it’s no surprise that after a brief dalliance with skinniness, the singer has once again packed the pounds. Clarkson now weighs in at 165lbs, which makes her a good 30lbs overweight for her height of 5′3″.

Star Magazine reports:

Kelly’s always favored a piece of cheesecake over perfection. “I’ve always been thicker,” she’s said. “I don’t believe in dieting.” And even now, says a friend, “She’s happy where she’s at. She doesn’t think being thin should be a big priority in her life.” Plus, she wants to continue to be a good role model for her more voluptuous fans. “She gets tons of fan letters telling her to stay curvy,” the source says. “The last thing she wants to do is betray those young women who look up to her by going on a crash diet.” But even though she’s just fine with being on the fuller side, Kelly’s starting to consider making a change. “She’s nervous about her health,” a friend reveals. She knows she needs to do something about the extra weight.”

In other words, she’s going to soon begin “working out” and in about 6 months she’ll be back to looking slim before ballooning again for the millionth time.

This week Lindsay Lohan has been cavorting around in Hawaii in a various bikinis, showing off her skin and bones.  She’s so skinny that the only thing that could cause such a drastic change in her appearance is drugs.  Sure, she’s also probably anorexic, but the drugs are really pushing off the weight.  According to the new issue of Us Weekly, Lindsay’s weight loss secret is in fact a drug, although not the illegal type you’d think.

LiLo’s weight loss drug of choice is Adderall, which is usually prescribed to treat narcolepsy and ADHD.  Apparently LiLo pops Adderalls like breath mints, which explains why she is wired for days at a time, is jittery and unable to concentrate, and why she also flips out at the drop of a dime.  Her eating habits aren’t all that good either.  She’ll eat just one meal every two days, and often lives on just soft drinks.

Lindsay is said to love being so think, and can’t stop looking at herself in the mirror.  When people start talking about how they can see her ribs, she gets even more giddy.

The reason she probably likes being so skinny is because it gets her attention.  It gets her attention from the media, and most importantly, Sam Ronson.

Alley managed to shed 75 pounds while working as their spokesperson, but has been struggling since.

A spokesperson for Jenny Craig said:

“Jenny Craig maintains a friendly relationship with Kirstie and we are proud of her accomplishments while she was on our program. Kirstie successfully lost 75 lbs and maintained that weight loss throughout our three-year relationship, which came to an end in December 2007.

We remain supportive of Kirstie, wish her nothing but the best and we would welcome her back at any time as a returning client.”

In other words, they’ve noticed her weight gain and aren’t offering to help her for free.  This time, Kirstie would have to be a paying client.
