"One time, we were at a party and I think she got really drunk, and she had just really derogatory things to say to me," Aguilera told the magazine. "But it was at that time that she had that breakdown, so she might have been very medicated."
(In 2001, Carey was hospitalized for exhaustion after several bizarre public appearances, including a near-striptease on MTV's TRL.)
In response to Aguilera's comments, Carey told Access Hollywood, "I had hoped that Christina was in a better place now than the last time I saw her, when she showed up uninvited at one of my parties and displayed questionable behavior.
"It is sad yet predictable that she would use my name at this time to reinvent past incidents for her promotional gain," Carey added. "It is in my heart to forgive and I will keep her in my prayers."
Aguilera, whose new album, Back to Basics, is due Aug. 15, seems ready for a truce. "I do not want any bad energy with anyone," she told Access when contacted for comment. "My intentions were not to upset Mariah with any statements that were published or taken out of context. I have all the respect in the world for her."
