The singer told New that his estranged wife's suggestion that he knew her attacker was untrue.
Andre said: "She said I did know about her claims that she's been raped twice and this was something I was aware of during our marriage.
"I'm really, truly sorry if this is something that happened to Kate in the past, but all I will say is I was not aware of it and it's not something we ever discussed."
She added: "When that story came out last week, it was the first I'd heard of it, and I was as shocked as everyone else.
"The only thing I knew about was the incident with the man in the park that she discussed on Piers Morgan's Life Stories earlier this year."
Price and Andre are believed to have filed cross decrees for divorce that will be heard by the High Court today.
