Lindsay and her sister Ali were taking surfing lessons last week and here are some pics of a very skinny Lohan at the beach.

Wow shes very very thin. Perhaps the recent break up with GF Samantha Ronson has made her lose even more weight. Although painful I’ve heard the break up diet results in drastic weight loss..

Lets hope the recent split doesn’t cause Lindsay to lose more weight from her already tiny frame

What’s your theory on Lindsays weight loss? Her ex boyfriend Aaron Carter has said..

“She’s been going through a rough time right now, family drama,” he tells Star magazine. “It can cause health problems and it can cause mental problems.”

Her rep has put it down to stress and told the media that on a photoshoot Lindsay ate two full meals.

Here’s the latest piccies

She’s definitely lost weight lately. The paparazzi have said that when she went out to lunch with her sister and some friends she didn’t eat anything. She turned down her sisters offer of a bite of her muffin and she sat there smoking.
