A transsexual woman who claims she had a three-week affair with suspected killer Luka Rocco Magnotta says he once told her he would do “anything to be famous.”

Nina Arsenault told CityNews in an exclusive interview that she met Magnotta when he was just 18 and working as a stripper at Remington’s on Yonge Street.

“I first met him as Angel, but then he told me his real name is Luka and he also referred to himself as Rocco,” she said.

“He was my very first lover after I started living as a transsexual,” she claimed.

Arsenault called Magnotta “very manipulative” and a “pathological liar.”

She also said he would make disturbing statements when intoxicated — words that are even more chilling in light of allegations that he killed cats and stabbed a man to death in Montreal before dismembering the body and mailing the victim’s body parts.

“He would joke about killing animals. He would joke about killing people, that he wanted to kill his family,” she recalled.

Arsenault also said Magnotta used methamphetamine, was fascinated with James Dean and Madonna, and would punch himself in the head while showering.

“He said, ‘I’m afraid when you look in my eyes…that you’ll see that there’s nothing inside of me.’ “

“To me he was a f****d up kid.”

Magnotta, 29, is currently the subject of a Canada-wide arrest warrant and was added to the Interpol most wanted list on Thursday.

Montreal police believe the Scarborough-born suspect has fled the country, and there have been reports suggesting he could be in France.
