Christina Aguilera regrets speaking openly about her feud with Mariah Carey.

The Dirrty singer revealed earlier this year that Carey had made nasty comments about her and been rude at a party, but now feels that she should have ignored her behaviour.

"She hasn't been nice to me, no," Christina told Allure magazine. "But honestly, I don't want to give her any more attention by even talking about it. Sometimes honesty is my downfall."
