IN a desperate bid to save her floundering network, Oprah Winfrey is planning to stage an elaborate televised wedding to her longtime love Stedman Graham – and she’s offered him a staggering $100 million “prenup” to go along with the scheme.

Oprah’s OWN network has been on a steady decline since it was launched in January 2011. Finan­cial analysts calculate the network could lose more than $140 million this year .

 “Oprah’s realized that the shows she’s created are just not attract­ing interest – the fans want to see HER,” said a TV industry insider. “So she’s devised a secret plan to save OWN by getting married to Stedman on live TV.”

The 58-year-old media mogul shared her bombshell idea with Stedman, 61, her boyfriend of more than 25 years, a few weeks ago at her estate in Califor­nia, a friend of Stedman’s revealed.

“It was a beautiful afternoon and they were walking hand-in-hand in her gardens,” disclosed the friend. “Oprah said, ‘There’s something I really need to ask you, Stedman.’

“She began to break down cry­ing, saying she had made a mess of OWN. Then Oprah looked at Stedman and said, ‘You’ve always been my knight in shining armor. Will you finally marry me?’

“Stedman was absolutely floored and a little shell-shocked, but he didn’t hesitate and joked, ‘I thought I was the one who asked YOU – 20 years ago! What’s the big rush all of a sudden?’

“They both laughed and hugged, and he began wiping away the tears from her eyes. He said to her, ‘You know I’d do anything for you, Oprah. You’ve always been my girl.’”

The friend also revealed that over dinner that evening, Oprah stunned Stedman when she told him she was planning on giving him a $100-million “prenup” for becoming “Mr. Oprah Winfrey.”

“Stedman told her, ‘You’re way too generous,’ but then joked, ‘Is this why you’ve waited all these years – because you didn’t want to change your name to Oprah Graham?’”

Despite the light-hearted nature of the conversation, Stedman was well aware of the seriousness of the situation.

“He knows the wedding idea may be the only thing that can keep Oprah from losing her struggling network,” said the friend.

“Stedman plans to present Oprah with a very special engagement ring that was given to him by his late mother Mary before she died. It’s a small diamond, but he knows that the sentimental value will make her feel proud to wear it.”

The Tv insider added: “By marrying Stedman she can not only give viewers a TV event that will rival the royal weddings, but also months of programming cov­ering everything from shopping for her gown and choosing the wedding site to selecting the food and band – everything down to en­graving the invitations.

“There’ll be the bridal showers, even Stedman’s bachelor party will be televised on OWN!”

All of this will lead to the blowout live wedding ceremony in the fall.

“She can even hold contests for lucky viewers to attend the wed­ding,” continued the friend. “The ceremony itself and reception can run for weeks – and then she can take Stedman on an around-the-world honey­moon and televise all the exotic places they go.”
