Oprah reveals her ultimate favourite thing

No stranger to waxing lyrical about her latest and greatest finds (we'll pause for Oprah's Favorite Things applause), Ms Oprah Winfrey has opened up to Vogue magazine about her ultimate 'thing.'

And there's a good chance you already have one in your home.

"I major in bathtubs," the businesswoman, talk show host and actress admits.

"I spend my time looking for the best possible bathtub a woman can buy."

Bourne out of a childhood promise to herself that if she ever could she would get herself a good tub, Oprah values ultimate luxury in a bath and even had one that was moulded and shaped to her body.

But if you're thinking of having a little soak in one of O's myriad bathtubs (who isn't?) you'd best ask the lady of the house if you're allowed.

"[My long-term partner] Stedman has never been in this one," Oprah says of a bath at her California property.

"When I was in Chicago, he would ask for permission: 'Can I get in your tub?' And I would say, 'Mmmmm… OK.'"  

As obsessed with baths as Oprah? Here's some to put on your wish list…
