Kim and Khloe Kardashian: That’s How They Roll, Yo

With the ever-growing success that they’ve been experiencing lately, the Kardashian sisters can afford to just skate by for a while.

Kim and Khloe Kardashian hit up the launch party for Pepsi’s new Throwback variety (now with sugar!) on Wednesday night, which was held at Los Angeles’ World on Wheels roller-skating rink.

Apropos of the retro theme, the Sisters Kardashian went vintage for the event, rocking headbands and leg warmers as they hit the floor.

They weren’t the only ones getting into the costume act. Kelly Osbourne was also on hand, flaunting a pair of awesomely bedazzled skates.

“I was so jealous!” Khloe writes on her official Web site. “I loved them.”

Hmm; perhaps Osbourne would agree to a skate-off for them?
