Kim Kardashian. Oprah Winfrey. Gwyneth Paltrow. Jay-Z. Which celebrity entrepreneur would you most want to get into business with?

The former Queen of Talk, Oprah Winfrey, was the clear winner, according to a poll of 750 business owners in the United States, the U.K. and Australia by Xero, which provides accounting software for small businesses.

Oprah, a media mogul with her own TV production company and an estimated net worth of $3 billion scored 40% of votes.

In second place (with 13%) was actress and entrepreneur Gwyneth Paltrow, who runs lifestyle company GOOP.

Xero gave small business owners a list of eight celebrity entrepreneurs to rank. Billionaire Mark Cuban, a judge on ABC's "Shark Tank" and actress Kate Hudson, co-founder of workout wear brand Fabletics, came in at No. 3 and No.4.

But perhaps the biggest surprise was who landed at the bottom of the list: Kim Kardashian. The reality star garnered 3.7% of votes.

When asked which celebrities should become full-time entrepreneurs and give up their other gigs, business owners voted for Beats cofounder Dr. Dre, Honest Company cofounder Jessica Alba and startup investor Ashton Kutcher.

Separately, business owners were also polled on celebrity entrepreneurs they least admired.

Kim Kardashian made an appearance on that list, too -- topping it with 56% of the votes.

Presidential candidate and real estate tycoon Donald Trump came in second, followed by Martha Stewart and Ashton Kutcher.

But Main Street entrepreneurs offered something extra for Trump in the survey -- their advice on how he could protect his businesses from bankruptcy.
