Amy Winehouse is back. She arrived in the U.K. from St. Lucia Monday, looking initially tearful to be home, but healthier than she has for ages, reports.

Winehouse, 25, who has been in the Caribbean island for much of the year is planning on catching up with friends and working on her new music. But most noticeable is her improved complexion and fuller figure.

“She is good. She has been looking after herself,” says a friend. “She did a lot of exercise and she has been eating better. Look at her — she is not what she was.”

Tales of her going on alcoholic benders are exaggerated, friends say. “She is Amy Winehouse and has a drink. But she has improved considerably.” The source adds, “She has had to cope with some huge problems, including her marriage of course.”
