Jay-Z and Ciara are gearing up for a tour this summer ... together. So far, five dates have been announced, as of Tuesday (May 12).

The first of the special summer dates will kick off July 3 in Las Vegas with a two-night stint at the Pearl at the Palms Casino Resort, and head off to Chicago and Atlanta.

Ciara revealed the news Monday night (May 11), when she blurted it out during a Twitter update: "I will say it because the information has been leaked. Me and Jay-Z will be doing a 10-city tour run together! More details coming soon!"

While five dates have been confirmed, a rep for Jay-Z told MTV that the tour would not include 10 cities.

In June, Ciara is scheduled to support Britney Spears on the European leg of the Circus tour.
