Christina Aguilera has been offered $3 million to become the new face of a dating website for curvy women.

The Fighter hit-maker has attracted attention with her fluctuating weight in recent months, but she recently spoke out to silence critics, insisting, "The challenge I've always had is being too thin, so I love that now I have a booty, and obviously I love showing my cleavage."

Now, bosses at The Big and the Beautiful website for plus-size singles have asked the pop star to front their firm.

In a letter, obtained by TMZ.com, former winner of America's Next Top Model and company president Whitney Thomas writes, "I have been following Ms. Aguilera's career and feel she would be a perfect fit as the new face of the brand... I hope she is interested in exploring this opportunity with us."

The 31 year old is not the first celebrity to receive an offer from the organization - soul sensation Adele was recently presented with a similar business opportunity, but she turned it down.
