K-Pop is hoping to make a huge crossover with T-ara N4. The girl group hung out with Chris Brown, and now they're opening for the 'Fine China' singer -- and also for Wiz Khalifa!

Billboard reports that T-ara N4's agents, Core Contents Media (CCM) confirmed that the ladies would open for Breezy tonight (May 26) in Las Vegas and that they opened for Khalifa on May 24, also in Sin City.

The news comes on the heels of rumors that T-ara N4 were releasing five different versions of their single 'Countryside Life' in the states, with each individually featuring Wiz Khalifa, Snoop Dogg, T-Pain, Ray-J and the Brown. However, none of that has happened yet -- though the ladies are indeed in talks with rappers to feature at some point.

Furthering their hip-hop cred? The gals will attend the 2013 BET Awards on June 30 and were snapped in a studio with T.I.!
