Substance abuse? Check. Passionate, tempestuous romance? Check. Now singer Amy Winehouse is following in Sid Vicious's footsteps in another way – by cutting her beloved's name into body.

In a video on Spin.com, Winehouse, 23, is seen posing for photographer Terry Richardson while scratching on her exposed midriff with a shard of a broken mirror.

In another clip, her husband, Blake Fielder-Civil, whom she wed in May, asks her, "How do you think the shoot's going, Baby?" "Really well, Baby," she replies sarcastically.

"What did you think about the broken glass?" he asks. In a childlike voice, Winehouse replies, "I wrote 'I love Blake' on my tummy." She lifts her shirt to bare her stomach, although the cuts are not visible on the video. "It's just chicken scratch," she says, as she and Fielder-Civil laugh.

The incident created some controversy in Winehouse's native England, where she is known for her self-destructive behavior (her hit "Rehab" is about her refusal to seek help for her drinking problem). Earlier in June, the tabloid News of the World reported that she and Fielder-Civil cut their arms together. Spin.com reports that the couple "have matching crisscross scars and scratches up and down their left arms," though says the marks are "presumably from a misbehaving house cat."

Both she and Fielder-Civil have permanently marked their bodies in tribute to each other – the Spin.com story notes that he has an "Amy" tattoo behind his right ear and an image of his wife as a mermaid inked on his right forearm; Winehouse has "Blake's" tattooed over her heart.
