Rapper Wiz Khalifa and model Amber Rose are to host their official wedding party this weekend (17-18Aug13), according to U.S. reports.

The Black and Yellow hitmaker and Rose welcomed a son in February (13) and married in July (13), but told fans they were waiting until later in the year (13) to throw a big bash to mark the nuptials.

According to PopCrush.com, the couple is preparing to celebrate with family and friends at a country club in Khalifa's hometown of Pittsburgh, Pennsylvania this weekend.

On Thursday (15Aug13), Rose posted a picture on Instagram.com of her wedding dress being delivered in a box marked "fragile".
