The Jonas Brothers kicked off their world tour this past Saturday, June 20th down at the new Cowboys Stadium in Dallas, TX. There were around 50,000 fans there to greet the trio and their openers (Honor Society and Jordin Sparks). As a special surprise to the fans, Miley Cyrus made a surprise appearance and sang “Before the Storm,” a song she collaborates with the Jonas Brothers on, which is featured on their new CD. If you want to see the Jonas Brothers and Miley Cyrus performing, it’s nothing a quick YouTube search can’t find. The Jonas Brothers will be hitting the stage at Rupp Arena on August 23rd, and Miley Cyrus will be doing the same on November 1st.
