These days, it's seems Lindsay Lohan is looking better than she has over the past few years -- she looks happy and together, often alongside girlfriend Samantha Ronson. But she also looks remarkably thinner -- not that the starlet was ever big or anything, but these days, it seems she could turn sideways and disappear. We could give her the benefit of the doubt and assume that she's 'naturally thin' and her weight loss is down to a healthy diet and exercise, but where's the fun in that? Plus, Lindsay's friends are saying otherwise.

According to FemaleFirst.co.uk, a source close to the actress says, "She is thinner than ever and we are concerned she is taking it too far. Lindsay's weight has always fluctuated, but since falling in love with Samantha Ronson -- who is naturally very slim -- Lindsay seems desperate to lose more weight."

What do you think? Is Lindsay's weight loss healthy?
