Victoria Glover, 39, was arrested at 5:30 p.m. Tuesday after she showed up at the stage door of the Metropolitan Opera house at Lincoln Center to ask Sills to be her bride.
Cops said Glover has been stalking Sills, who is married and has two grown children, since November, when she began calling the soprano's office at the Met.
"Sills is aware of the defendant's efforts to contact her . . . and has experienced fear for her physical safety as a result," NYPD Detective Carl Roadarmel wrote in a report
