Tyra Banks has been named the hardest-working person in showbusiness in a new online poll.

The model, talk show host and TV presenter has become a minimogul since she stepped down from the catwalk in 2006 - and now she has landed at the top of a new survey aimed at finding America's hardest-working celebrity.

Banks beat American Idol host and DJ Ryan Seacrest, Jennifer Lopez, Heidi Klum and Sean `Diddy' Combs to claim the top spot on Parade.com's annual Summer Pop Culture poll.

The poll also claimed Oprah Winfrey as the celebrity most people would like as a next-door neighbour and Nicole Richie beat Mel Gibson and Tom Cruise to become the celebrity with the Most Improved Reputation.

Meanwhile, voters chose Jennifer Aniston and John Mayer as the Most Unlikely Couple and Halle Berry beat out Jennifer Lopez and Jessica Alba to claim the Hottest New Mama crown.
