Back on track: Healthier Amy Winehouse piles on the pounds

She has become known almost as much for her gaunt appearance as her music.

But now it seems Amy Winehouse is finally on the up.

Her sunken cheeks had filled out and her skin had a more healthy glow as she was pictured out in the capital.

Her hair, seen tangled and dishevelled so many times, was neatly tied up with a bow.

An onlooker said: 'She seemed to have colour in her cheeks for once and looked really perky. Her face seemed to have filled out a little.

'Hopefully this means she has finally turned a corner.'

Perhaps the singer is finally heeding advice to improve her health after a series of scares.

Just a few weeks ago, she arrived at a pub to celebrate her 25th birthday underdressed and looking thinner than ever.

Earlier this year, Miss Winehouse, who has fought a yearlong addiction to crack cocaine and heroin, collapsed with convulsions after a suspected overdose.

She has also had treatment for a lung condition and last year suffered 'severe exhaustion'.

Drug dealers who sold a video of Miss Winehouse apparently smoking crack for £50,000 were warned by a court yesterday that the money could be seized.
