Last week, Mathew Knowles broke the news that Beyoncé will embark on a 110-date world tour that will begin in April 2009 and trek through Canada, Europe, the U.S. (with a one-week stint in Las Vegas), Mexico, South America, Japan, Africa, and Australia. But what you didn’t hear was that Beyoncé won’t be the only Knowles on the road.

Discussions are under way for Solange to join her big sis’ on tour. After seeing the elder Knowles rock arenas, fans would be able to go to a more intimate location and watch Solange perform at an official “after-party.” Specific details have yet to be announced.

Beyoncé is scheduled to release her third album I Am… Sasha Fierce on November 18th, while Solange’s sophomore release SoL-AngeL and The Hadley St. Dreams is available now.
