Brad Pitt and Jennifer Lopez have the 'best butts in Hollywood', according to a new poll. The Hollywood heartthrob and the Latino beauty's behinds were deemed the most impressive in the survey for American magazine Oxygen. In the male section, Brad beat 'Be Cool' star Dwayne Johnson and Vin Diesel into first place with 34.4 per cent of the vote. While in the female poll, J.Lo fought it out with Bootylicious Beyoncé Knowles for the most desirable derriere - edging her out with 19.58 per cent compared to the Destiny's Child star's 16.67 per cent. Angelina Jolie, who was recently voted the world's sexiest woman by America's FHM magazine, came third with just under nine per cent of the vote.
