LOS ANGELES — Miley Cyrus is stepping up for a good cause.

The 17-year-old Hannah Montana star has put together an online auction that will assist earthquake relief efforts in Haiti.

The eBay auction, which runs Feb. 8-18, includes the Herve Leger dress that Cyrus wore to the recent Grammy Awards, as well as two tickets to the Hollywood premiere of her upcoming film, The Last Song.

HOLLYWOOD, Calif. — Miley Cyrus is catching heat for another risqué dance, this one featuring her younger sister, Noah.

In a new viral video for the Hannah Montana star's official fan site, mileyworld.com, Miley is seen urging her 9-year-old sibling to perform a rendition of Akon's raunchy hit, "Smack That."

The video is the latest in a series of sex-charged controversies that have surrounding the showbiz family. Last year, Miley drew criticism when she posed semi-nude for a photo spread in Vanity Fair. She was also accused of pushing the limits with a provocative pole dance at the Teen Choice Awards in August.

HOLLYWOOD, Calif. — Miley Cyrus slipped into a pink bikini on Thursday, but it was her seemingly new tattoo that created the bigger buzz.

The Hannah Montana star was photographed with a tattoo that reads "Just Breathe" under her left breast as she lounged poolside with friends at the Fountainbleau Resort in Miami Beach.

Cyrus, who turned 17 on Nov. 23, has yet to confirm whether the tattoo is a permanent fixture. By law, the legal age to get inked in the U.S. is 18.
