Punchy.

Perpetually troubled singer Amy Winehouse was arreted Friday for assaulting two men early Wednesday morning. The alleged assaults occurred over the course of two separate scuffles: one inside a bar, where Winehouse reportedly punched a man in the stomach; the second attack came later, when the singer allegedly head-butted a man who tried to grab her cab. The latter, we think, is understandable. [NYDN]
