?T-ara N4 are going forward with their promotions in America this week. 

Agency Core Contents Media announced that the girls' schedule in the States has been moved up. They'll be heading to the United States on the 23rd, and will arrive in Los Angeles on the 25th just ahead of Chris Brown's concert in Las Vegas the following day. 

T-ara N4 have been invited as special guest performers at the American singer's event, where they'll be working with his choreography team Flii Stylz. They're also slated to perform at hip hop star Wiz Khalifa's concert on the 24th. Wiz Khalifa himself will be collaborating with T-ara N4 on stage as well.

Ahead of the concerts, T-ara N4 commented, "As it's the first reveal of our song 'Countryside Life' in America, we're very nervous and excited, and we still can't believe it's happening."
