Jackman was working out in a gym Saturday morning in Manhattan's West Village neighborhood when a woman rushed in, crying and shouting that she loved him.
Police say 47-year-old Kathleen Thurston pulled out a razor filled with hair and threw it at him, then fled and was arrested several blocks from the gym. Jackman wasn't hurt.
Thurston is awaiting arraignment on the stalking charge.
Police say she has gone near Jackman and his family before.
The "X-Men" star said the run-in was frightening, and that his primary concern is his family.
