Lindsay Lohan and little sister Ali did some shopping this weekend in New York where Lindsay frightened onlookers with her increasingly rail-thin figure. It’s gotten to the point where you can see her spine.

Lindsay’s spine and shoulder-blades were painfully visible as she tried on clothes, whilst her waist and thighs were almost non-existent in a grey leotard teamed with her trademark leggings.

Lindsay and Samantha Ronson are having the effect of a diet pill on each other, according to one friend. The more these girls hang out, the skinnier they both seem to be getting.

“Sam has gotten so thin from Red Bull, cigarettes, and stress related to life with Lindsay,” a friend of Ronson’s told OK!. “Lindsay is bad for Sam’s health.”

According to the pal, the weight loss isn’t just a mere coincidence. Instead, the two have competed at being skinny ever since they first hooked up.

“Lindsay is obsessed with her weight; it’s hard not to be with another woman and not compare bodies,” the friend said. “And Sam herself loves being skinny and prefers Lindsay super-lean.”

Lindsay’s shopping spree may be to celebrate recent rumors of being cast as Snow White in the upcoming film The Stepsister Scheme, an adaptation of the classic Disney tale.

This would be the first major work that Lindsay has been done since she shot Labor Pains last summer, which has yet to be released.

Ali Lohan is so desperate to follow in her big sister’s footsteps that she took to the turntables last night just like the rehabbed 21-year-old does when she wants attention. Lindsay Lohan brought her 14-year-old mini me to a photography exhibit she was hosting last night at the Atelier in NYC so she could learn the ropes of stardom (and the pap poses).

Ali and mother Dina have a new reality show deal with the E! network.  The show will be called Living Lohan and is set to premiere this summer.

Ali has been talking about how desperate she is to be famous.

“I want it so bad. So bad you don’t even know. And now, it’s actually happening,” Ali told Teen Vogue this month. “I’ve already been asked for my autograph, and it’s just a really good feeling to have.”

Are you getting a bad feeling about Ali’s future too???  A fixation with fame and an enabling mother didn’t work out so well for Lindsay’s health.

The E! reality show starring Dina Lohan and her 14-year-old daughter, Ali, finally has a name — Living Lohan — and a summer premiere date.

“Viewers will go inside the Lohan’s Long Island home for the first time to follow Dina as she works double duty as mom and manager to help Ali try to follow in her big sister [Lindsay’s] famous footsteps,” a press release for the show says.  No word yet if Lindsay will be making any appearances on the show.

Cameras will also follow the duo to Vegas as Ali records an album.

“Dina is determined to help each of her four kids fulfill their dreams and refuses to live in fear of what others may think, despite being under the paparazzi microscope,” the press release adds.

“I want it so bad. So bad you don’t even know. And now, it’s actually happening,” Ali told Teen Vogue this month. “I’ve already been asked for my autograph, and it’s just a really good feeling to have.”

This has disaster written all over it!
