Christina Aguilera's Too-Tight AMAs Dress: Fashion Turkey of the Week?

What are fashion fans most thankful for this week?

Not Christina Aguilera's American Music Awards outfit!

After going pants-less last month, the "Dirrty" singer sparked yet another style uproar performing in L.A. Sunday in a white, way-too-tight bandage dress by Herve Leger; the frock's less-than-flattering fit even provoked fans to wonder whether the 30-year-old singer and Voice mentor is expecting.

For that talked-about performance look, Aguilera is among this week's "Fashion Turkeys" in a Thanksgiving edition of Fashion Police, hosted by Us Weekly's Andrea Lavinthal and Justin Ravitz.

But Aguilera's not the only superstar to win the dubious honor. Fellow AMA performer Jennifer Lopez may have gone too over-the-top with five super-sexy outfits -- including one sparkly, flesh-toned body suit that recalled (ripped off?) Britney Spears' "Toxic" days.

Also sparkly, and maybe not in a good way? Kim Kardashian, in the front row for brother Rob Kardashian's Dancing with the Stars Monday finale night in a sequined tuxedo.
