In case you missed the last episode of ABC's The Bachelor, Juan Pablo Galavis and six contestants were flown to Seoul, South Korea to meet K-pop super stars 2NE1. At first, the group thought they were just meeting 2NE1 and maybe learning a few cool dance moves, but then they found out that they would be the backup dancers for the K-Pop group's performance in Seoul’s Time Square Mall.

The contestants and 2NE1 performed their hit "I Am the Best," and from the clips below you can see contestants Danielle, Cassandra, Nikki, Chelsie, Kat, Elise and Juan Pablo rock out to the song. By all accounts the performance was a huge success as afterwards the song rocketed to number four on the US iTunes Electronic Charts.
