Katie Couric is rattled by mysterious 911 calls being made from her late husband Jay Monahan’s landline.

The calls happen Tuesdays at 2 a.m., various sources told the New York Daily News, and are placed from the line in Couric’s apartment that belonged to her husband.

“It’s happened like three times the last three weeks,” Couric reportedly told the audience during a break in taping her talk show “Katie.”

“Every day, every time at 2 a.m. on Tuesday morning. I was out of town the last time it happened and apparently it happened before when nobody was home,” she said.

Police sources told the Daily News there have been at least 10 calls placed from the line and each time a patrol car has responded to the calls.

Couric told the studio audience at her show she was awakened after the last call, because emergency operators returned the call, causing the phone to ring in her apartment.  

Audience members told the Daily News Couric said she was so frantic about the calls that she contacted Police Commissioner Ray Kelly for help.

“So I called Ray Kelly, who I know just through the years seeing at different things. ‘Ray, this is so weird but can you help me? I don’t know what to do,’” Couric said, according to a member of the audience.

A source close to the Couric told the newspaper that the star spoke to Kelly briefly and he directed her to someone who could investigate the situation.

Police say they are investigating whether something's wrong with her phone or if Couric is the victim of a high-tech prankster.
