Police officers arrested 47-year-old Katherine Thurston after she approached the 'Les Miserables' star at his gym and threw the razor at him, reported New York Daily News.
Thurston told cops she came to New York two months ago determined to become Jackman's second wife.
"I want to marry him. This is not against the law. It is not against the law to have two wives," Thurston told NYPD detective Frank Francisco.
Thurston was arraigned in Manhattan Criminal Court on misdemeanour charges of menacing, stalking, harassment and trespassing. She was also charged with criminal possession of a weapon - the black electric shaver she went after Jackman with.

"The most important thing is the security of my family. I am very appreciative of what the DA is doing," he said.
Thurston claimed she started emailing Jackman about a year ago. On March 6, Thurston went to the school where Jackman's seven-year-old daughter, Ava, is enrolled and confronted the actor's wife, Deborra-Lee Furness, outside.
"I am going to marry your husband," she told Furness, according to police.
