An an's affair?

Cao Jun has asserted that he did not have an affair with Anan. His statement is credible - it would seem that An an (pumpkins mother) was probably trying to make Nai Yin Jealous.
Cao Jun said
1) He has two children, 17-year-old daughter, and son 21 months - so her blog was incorrect about that
2. He asserts he was not in Wellington when she said he was there and he did not have opportunity to be there
3. Her photos of him are taken from the public domain
4. He asserted his right to defend himself against defamation (not that that makes his statement any more or less credible) but his defense sounds very much like that of an innocent man.
