The younger sister of the Duchess of Cambridge acted as maid of honour at the nuptials of Kate and Prince William and has received a great deal of attention after her figure-hugging gown highlighted her bottom.
Since the April 29 ceremony, Pippa has been tipped for a 'Rear of the Year' award and was reportedly offered $5 million (£3.05 million) to appear in a porn film.
However, speaking to The Sun, Tempah admitted that he has not been won over by Pippa's derriere.
"I've not actually got what all the fuss is about. I prefer a bigger bum. I'm definitely a bum man but she's not doing it for me. Sorry Pippa," he said.
However, Tempah admitted that Cheryl Cole is one of his crushes, saying: "I fancy her, she's a good looking girl."
