The British pop star mockingly toasted the troubled singer - who entered rehab last week after collapsing from an alleged cocktail of ecstasy, cocaine, ketamine and alcohol - during her V-Festival set in Chelmsford.

Lily poured herself a shot of Jagermeister, a 70 percent proof liqueur, and raised her glass, saying: "It's the end of the weekend, you have got to have a drink."

"Here's to Amy Winehouse.. ha!"

The 22-year-old singer also took another veiled dig at shockingly thin Amy - who is reportedly addicted to heroin - when she attacked skinny celebrities.

Introducing her song "Everything's Just Wonderful," she said: "All these skinny girls in the magazines, 'Look at me, look at me' - heroin addicts!"

"You are not that skinny unless you have an eating disorder or a drug habit."

Lily - who has scrapped her US tour after her visa was revoked at Los Angeles airport earlier this month - also insisted she is glad she has been banned from the US, because she can spend more time with her lover DJ Seb Chew.

She said: "I couldn't care less if I never go to America again. I would rather be with my man."

"I've been banned from America. That's nice. Oh well, that means I can't go back there. Good."

The "Smile" singer then added in an American twang: "I'm going to dedicate this to the US. Obviously I'm really sad I can't do my US tour."

"Shame on you, the US Immigration Service."

Lily also branded US President George Bush a "f***ing ****" during her earlier V-Festival set in Stafford on Saturday
