Christina Aguilera is fighting back.

In the new issue of Billboard magazine, the “Your Body” singer says she felt an enormous amount of pressure from record executives to be skinny. But she says she's no longer obeying their rules.

"You’re working with a fat girl," the singer says she told music execs when she began working on her upcoming album, Lotus. "Know it now and get over it."

The 31-year-old admits that during 2002 she grew tired of the image she alleges her label, RCA Records, wanted her to maintain.

"During the promotion of Stripped in 2002, I got tired of being a skinny white girl," Christina said. "I’m Ecuadorian,  but people felt so safe passing me off as a skinny blue-eyed white girl."

She also reveals that execs called an emergency meeting after the five-time Grammy Award winner showed up 15 pounds heavier and full of piercings back then.

"They told me I would affect a lot of people if I gained weight — the production, musical directors," she says. "[They claimed] people I toured with would also miss out if I gained weight because I would sell no records or tickets for my shows. I was young, so I lost the weight quickly and was toothpick-thin during Back to Basics promos and touring."

But now in 2012, Christina, who has a 4-year-old son, Max, is staying true to herself and her body.

"They need a reminder sometimes that I don't belong to them. It’s my body," she shares. "My body can't put anyone in jeopardy of not making money anymore — my body is just not on the table that way anymore."
