Ananova:

Brad Pitt and Jennifer Lopez have topped a poll to find the "best butts in Hollywood".

Readers of American magazine Oxygen voted the pair to have the most impressive behinds for the mag's June issue.

In the male section readers put 41-year-old Pitt way out in front with 34.4 per cent of the vote.

Second place was Be Cool star Dwayne "The Rock" Johnson with just over 10 per cent of the votes, while third was xXx star Vin Diesel with just over six per cent.

There was a tighter battle to find the best female butt.

Lopez, 34, just pipped Destiny Child's Bootylicious Beyonce, 23, with the pair polling 19.58 and 16.67 per cent respectively.

Angelina Jolie, recently voted Sexiest Single Mother and Pitt's co-star in the upcoming Mr

and Mrs Smith, came third winning just under nine per cent of the vote.
