A RETIRED media executive is being sued by his ex-mistress for refusing to leave his wife — who told him she’d rather “see them bury you six feet under” than let him go, according to a lawsuit.

And because the scorned other woman couldn’t have her man, she wants $US2 million ($2.6 million) instead.

Theodora Lee Corsell, 67, is suing James Greenwald, 88, for six years of unpaid work and because he wouldn’t cross his angry wife, according to The New York Post.

“According to Greenwald, [his wife] Marilee told him, ‘I will see them bury you six feet under before I grant you a divorce. I’m the last Mrs Greenwald’, ” Ms Corsell recounts in court papers filed in a New York City court.

The retired fundraiser says she was both professionally and romantically involved with Mr Greenwald, although he continued to live with his 77-year-old second wife on Park Avenue amid the six-year dalliance.

Mr Greenwald headed Katz Communications, a national TV and radio sales advertising company, in the 1970s through the 1990s.

Ms Corsell was Mr Greenwald’s glorified gofer over the last six years. She handled everything from getting rid of unused New York Giants tickets to promoting his unpublished memoir.

She even helped him quash a $US3 million threat by one of Mr Greenwald’s other mistresses — who planned to out him to his wife, ­according to court papers.

Then she zeroed in on getting him divorced.

Ms Corsell, by her own admission in court papers, dug up information on Marilee’s telephone calls and purchases, but the work was all for naught.

Mr Greenwald’s lawyer, Steven Mintz, said his client “remains happily married to his wife” and called the suit a “shameless shakedown”.

His co-counsel, Alton Abramo­witz, declined to address the specific allegations in Ms Corsell’s lawsuit.

Ms Corsell’s suit says Mr Greenwald’s other mistress, identified as Ms X in court papers, was demanding he leave her $US3 million in his will because he made $US300 million off the sale of Katz.

For all her hard work, Mr Greenwald promised Ms Corsell, “I owe you everything and I will compensate you,” her suit says.

She’s tagged the “reasonable value” of her “services” at $US2 million.

She claims she’s due the money because her “professional services ... were separate and apart from ... the parties’ romantic relationship.”
