You know BoA's latest US track "Crazy About," produced by Sean Garrett?

Well, because it would be difficult for Sean to attend, BoA has personally requested that Amber of new SM girl group f(x), join her to perform the rap portion of the track! Lots of love in the SM girl group family lately.

The performance will be on October 10th, at 5:00pm in Tokyo. I'm sure there will be many special surprises, so stay tuned!

Thanks to ahra for the tip.
