Vanna White may have joined "Wheel of Fortune" more than 40 years ago, but the veteran letter turner still sometimes gets the jitters on the air — and the reason why may surprise you.

As Pat Sajak has left "Wheel of Fortune," Vanna White is reflecting on her position with the game show and feels that "they could do it without me." However, there is one reason why the acclaimed show still "needs" her.

The 'Wheel of Fortune' icon tends to keep her personal life close to the vest, but she couldn't help but reference partner John Donaldson on a recent episode.

Ryan Seacrest's first episode as host of "Wheel of Fortune" airs Sept. 9, as he takes over for Pat Sajak for the show's 42nd season with Vanna White.

Wheel of Fortune's hostess with the mostest, Vanna White, has admitted that the show could continue to spin without her. The game show staple recently joked about her place behind the wheel while looking back on how things have changed over the years since she's been there.

But there’s one part of the show that will hopefully always stay the same: Vanna White turning the letters. White reflected on her career of 40 years turning letters on the hit game show beside her longtime co-host in a new interview with Parade.
