Pippa Middleton is back in the news with the release of her party planning book, Celebrate: A Year of Festivities for Family and Friends. As we reported over the weekend, Pippa has little doubt that at least some of her book sales can be attributed to her world-famous rump.

Since she brought it up, we thought it’d be a good time to run a little poll to gauge just how much Pippa’s tush is trending. So, who has the better butt...

Pippa or Heather Morris (Brittany) from Glee?
