Their sister is already a huge tabloid and blog star, and now they wanna big like big sis. Kim Kardashian's sisters, Khloe and Kourtney, are reportedly getting their own reality show.

According to Us Magazine, the Kardashian sisters -- who already star on "Keeping Up With The Kardashians -- have landed a new show with E! called "Kourtney and Khloe in Miami", in which cameras follow the sisters to south Florida as they open a new Dash boutique.

The title is still tentative, but it is expected to debut sometime in August.

During the first season, the girls try to focus on designing and hiring staffers for their new store, but get sucked into South Beach's famous party scene.

Then, Khloe is offered an opportunity to host a local late-night radio talk show, which causes fights between her and serious sis Kourtney -- who wants her to focus on their store.

"We knew fans could not miss out on this drama-filled duo as they invade such a beautiful, vibrant and notoriously wild city as Miami," E!'s Executive Vice President Lisa Berger told Us Magazine.

The show will, of course, feature cameos from the whole Kardashian family.
