12 celebrities with fluctuating weight (With Pictures)

3. Christina Aguilera

When Christina Aguilera started her career, some people said she was too thin. And they weren’t wrong; in the “Genie in a Bottle” video she’s slim as a knife. But as her career took off, so did her weight.

It wasn’t long before the “Dirrty” girl started putting on weight. But she lost it all for her role inBurlesque, a movie about a young girl from Iowa who seeks fame in L.A. In January of 2010, she was reported to be “rail thin.” But, once again, she started packing on the pounds, or, as TMZ says, “porked up.”

As the great Aretha Franklin taught us, your body don’t matter when your voice is that good, but just for peace of mind, Aguilera should try to stick with one silhouette.
