Halfway through Moves Like Jagger, her duet with Maroon 5, Christina joined her Voice co-mentor Adam Levine on stage wearing a dress so tight you could not only see what she had for dinner, but also where her Spanx ended.

Now, I am in now way calling Christina Aguilera fat. Because she's not. Let's get that straight. But at the same time we also need to acknowledge that she's not stick thin either. Anyone with eyes will tell you that -- but I'm starting to think someone needs to tell Christina...

She has one problem: wardrobe.

A style intervention is sorely needed -- we've gotta stop the girl from wearing Herve Leger by Max Azria bandage dresses! And, seriously, Max ... you gotta use some discretion when it comes to who can wear your designs because this isn't helping your brand or hers.

I'd love to see her into something structured, like a Vivienne Westwood gown. Now that is a woman who knows how to design for real women. Why else would Christina Hendricks be the face of the label?!?
