Nearly a decade after calling off her last engagement, VANNA WHITE is finally ready to walk down the aisle again!

The “Wheel of Fortune” letter-turner, 57, expects a marriage proposal from handsome beau John Donaldson, a building developer, sources told The National ENQUIRER.

Following a super-secret three-year romance, Vanna recently made their relationship public, with 55-year-old John escorting her to the Carousel of Hope Ball in Beverly Hills.

“Vanna has been unlucky in love – that is, until John came into her life,” an insider told The ENQUIRER.

Added a source: “Vanna expects a marriage proposal – probably for Valentine’s Day, with a small family-only destination wedding likely in the spring.” 

Vanna came down with a case of cold feet after announcing her engagement to her last boyfriend, banker Michael Kaye, with great fanfare.

She broke the news on “Wheel of Fortune” in 2004, but the couple split in 2006.

“She’s really fallen hard for John, who used to be something of a ladies’ man,” added the source.

“But he’s only had eyes for Vanna since they met. She’s taken it slowly, but it will end in a wedding this year.”
