'Wheel of Fortune' star Vanna White says fans always ask her the same question when they meet her

She revealed: "[They say], 'Can I buy a vowel?' And I love it.

"And 42 years later, vowels have not changed price! $250 - no inflation!"

Vanna - who has two children, 30-year-old real estate agent son Nikko, and 28-year-old tattoo artist daughter Gigi, with her ex-film producer husband George Santo Pietro - has been described as having a comforting presence, and she always aims to put the 'Wheel of Fortune' contestants at ease by telling them to "pretend like you're in your living room".

Speaking about how the contenders feel on the show - which is also hosted by Ryan Seacrest - Vanna said: "People aren't familiar with TV and all the cameras we have.

"There are 200 people in the audience and they don't want to make a fool of themselves on TV. And it's hard!

"When you're standing at home in your living room, it's always your turn.

"When you're there, the puzzle board is like 20 feet away, and, "Oh my gosh - where am I?"

"They do quite well considering the circumstances.

"When I first get to work in the morning, I go in and say hello to them when they're all getting in.

"I say, 'Buy vowels, don't be nervous, and pretend like you're in your living room.'

"I give them a little pep talk before they go on."

Vanna's own TV habits include being a regular viewer of 'House Hunters International' and ABC reality series 'The Golden Bachelor'.

In an interview with Collider.com, she said: "I like watching 'House Hunters International'. I feel like I'm traveling.

"I'm in Switzerland and Portugal and all these places - that's kind of my little escape.

"I also watch 'The Golden Bachelor'. I'm taken!

"I've been with my boyfriend for 15 years, but it's fun to see that, too."

Vanna is in a relationship with contractor John Donaldson who she met through friends.
