Billie Piper attended Awesome Con in Washington DC over the weekend. During her Q&A session a boy approached the mic and said that he had been offered $20 by his mum if he dared to ask her who was the best kisser out of David Tennant and Christopher Eccleston.
"I think I've kissed David more," said Billie. "So I think we are more practiced, well versed, and therefore our technique is somewhat better."
The child in fact made $100 from his parents.
