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

The Fighter hitmaker 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.
