Lindsay Lohan appears to be wasting away before our very eyes.

Since splitting with Samantha Ronson the Mean Girls and Herbie: Fully Loaded star has lost even more weight.

The Hollywood wild child - who has battled drink and drug problems in the past - stepped out with younger sister Ali yesterday bound for the Ellen DeGeneres show in Toluca Lake.

And her thigh-skimming flower print dress showing off her bony frame and stick thin legs.

In the two weeks since the split Lindsay has been spotted partying hard, hitting up to six different LA clubs a night.

One pal said to The Sun: “She barely slept for the first week. We were hoping things would improve, but she is still not sleeping or eating properly.”

The friend went on: “She has returned to her most dangerous behaviour. We are all looking out for the signs of self-harm too — we have been there before. Rehab looks like the only option.”
