Amy Winehouse was admitted to hospital on Sunday following a fall which left her with injuries to her face and ribs, The Sun reports.
The Back to Black star - who is due to remarry her ex-husband in the summer, was taken to a private clinic in London after taking a tumble.
"She'd had a few (drinks). At first she thought she had broken something, so got her security to take her to hospital. The doctors were worried she might be concussed because she had a big bump on her head and a cut above her eye," a source tells the newspaper.
Her injuries were described as "not serious" but her agent added: "She really likes the clinic so may stay a few days."
