Khloe and Kourtney Kardashian are taking their show on the road – to Miami, actually – but the lesser portions of the Kardashian trifecta will stop by Las Vegas this weekend before they relocate out East.

The two will appear alongside NBA great Robert Horry on Saturday at Sapphire Pool at the Rio as the adults-only pool opens for the 2009 season.

The opening day soirée is open to the public and kicks off at 7 p.m. The three-hour party will support the Prostate Cancer Foundation and admission is by donation, with a $10 minimum.

The sisters, who currently co-star alongside their prettier and more famous sibling, Kim, on E!’s “Keeping Up With the Kardashians” are getting ready to leave the Kardashian compound in LA and relocate to a space of their own on Miami’s South Beach.

The move comes as they prepare to branch out on their own to open a second location of their LA.-based boutique, Dash.

In typical Kardashian fashion, all of the trials and tribulations of the sisters’ east coast adventures will be documented and dramatized in a new reality spin-off series of their own, “Kourtney and Khloe in Miami.”

The show is expected to make its debut on E! in August.
