Curvy singers Jennifer Lopez and Shakira rounded out the list of the "World's Best Bum 2010."

Both voluptuous superstars lost to reality star Kim Kardashian in the end.

But J.Lo came right, um, behind her on the list. "SheWolf" Shakira finished sixth in the survey, conducted by England-based publication "The Sun" on their Web site.

The Iris Chacón wannabes have been making headlines.

The Puerto Rican “American Idol” judge is allegedly being sued by her first ex-husband’s girlfriend Claudia Vásquez, who filed a lawsuit against Lopez Wednesday in Los Angeles. Entertainment media outlet RadarOnline.com claims that Vásquez is upset because the pop star allegedly “interfered with a motion picture contract.”

As for the sultry Shakira, the Barranquillera has set out on a new “adventure” as a children’s book author.

Her new book titled, “Dora the Explorer in the International Day of School Adventure,” is a tale about Dora and her partner, Boots, going through multiple experiences, collecting school supplies and other needed materials that schools lack.

Revenue from the book will be given to Shakira’s “Pies Descalzos” non-profit, which strives for every child to receive an education early on.
