Two Australian DJs that prank-called the British hospital where the pregnant Duchess of Cambridge was treated apologized through tears on Monday after the nurse who transferred their call apprently committed suicide.

2DayFM radio hosts Mel Greig and Michael Christian's call -- in which they impersonated Queen Elizabeth II and Prince Charles -- broadcast confidential information about Kate Middleton. The nurse who took their call was found dead, sparking worldwide outrage from people who believe the prank call was a factor.

Southern Cross Austereo, which owns 2DayFM, said in a statement Monday that it had ended Greig and Christian's show and that there would be a company-wide suspension of prank calls. The DJs themselves remain suspended.

"There's not a minute that goes by that we don't think about her family and what they must be going through," Mel Greig told Australia's "A Current Affair" as her voice shook. "And the thought that we may have played a part in that is gut-wrenching."

She said she was "very sorry and saddened" for the nurse's two children.

In another interview with the show "Today Tonight," Christian also apologized.

“I’m gutted, shattered, heartbroken,” Christian said, adding, “We’re still trying to get our heads around everything, trying to make sense with the situation.”

Both DJs began sobbing when asked about the moment they learned that the nurse, Jacintha Saldanha, was dead. But they said they did not have second thoughts before they aired tha call, and that those above them at the radio station chose to air it.
