According to a letter to Aguilera's rep from site president Whitney Thompson, the first-ever plus-size winner of America's Next Top Model, Xtina is a great example of the company's "beauty at any size" ideal.
"I have been following Ms. Aguilera's career and feel she would be a perfect fit as the new face of the brand," Thompson, 25, writes.
In exchange for the $3 million, the letter states, Aguilera would be expected to participate in one television commercial, one radio spot, two photo shoots, and four public appearances in which she endorses The Big and the Beautiful. Additionally, she would agree to put her Grammy-winning talents to work on a new site jingle.
Aguilera -- who has been dating production assistant Matthew Rutler, 27, since late 2010 -- has yet to comment on the offer. But she's been plenty vocal in the past about embracing her fluctuating figure.
Speaking at a TCA press conference earlier this year, the songstress said of her body: "I've been on all spectrums. You can never be too perfect, too thin, too curvy, too voluptuous...As long as I'm happy in my own skin, that's all I need...I have a boyfriend who loves my body. I love my body. My soon is healthy and happy. That's all that matters."
She exhibited even more self-assurance in the October issue of Lucky. "The challenge I've always had is being too thin, so I love that now I have a booty," the Voice mentor told the magazine. "And, obviously, I love showing my cleavage...if you can work it and you can own it, that confidence is going to shine through."
