Sister BFF is the new single from the twins. It is about having your sister as your Best Friend Forever, even though sometimes she is very annoying and have some different tastes generally it has a good side. It is a great fun, bouncy pop song with some great harmonies and even better counterpoint towards the end of the song. You can also clearly tell that the girls voices are maturing and have a more adult sound but they still retain their youthful energy and the song is targeted at their younger audience. The video is excellent fun to watch, and looks like it was more fun to make, with a lot of energetic dancing, lots of costume changes, and a lot of different settings and once the music has finished continue watching for some outtakes from the recording that shows that the girls aren’t always as well co-ordinated as they appear in the film clip.You can follow Mylène & Rosanne on their Website, on Facebook, on their Facebook page, on Twitter, and on their YouTube channel.
