Well this is what they had written:

{This pair of twin sisters by the way, are the latest artistes to be rolled out by Ocean Butterflies International (ob-i), founded by famous local musician, Billy Koh (许环良). ob-i is also the recording company that successfully made JJ Lin (林俊杰) the big star he is now, in case you don’t know.
The twins were talent-spotted by ob-i from its music school when they were 13 years-old. Marked for stardom, they were sent to Taipei, Tokyo and Beijing for grooming for 6 months since June 2007, last year.
After taking time to read through their older blog entries today, I finally realised what was wrong - ob-i made the girls dropped out of secondary school to pursue a music career with them.
You can read what the girls have to say about this in their own words on their blog:
"We need to hand in our application to drop out of school to our form teacher today. However, ob-i requested us to keep the reason for dropping out a secret. Hence we were very frightened. We were worried our teacher will ask too many questions. We went to approach our teacher after school with a group of friends. We lied that we were dropping out in order to purse our studies overseas. With the help of our friends, our teacher did not discover we were lying."

Well they are from yio chu kang secondary wonder did anyone know them lol. Watch their videos in youtube and heard them sing and dance their songs i would only say ok only but what surprise me was they are quite good at singing, no joke and on top of that the dance real well. I donno why maybe because they are twins so they can coordinate very well which make the dance very nice and as for two 16 years old to dance till so hip hop blown my mind lol i think i dance like them i will break my bones haha. The only sad part was that they drop out of sch to pursue their career hmm like what xiao zhu said yan yi quan is not a good path to walk once you cannot make it, it will be hard to have a comeback and they are so young and what if i mean what if (no offence to their fans) they could not make it and without a cert. and come back to singapore? as you all know lah singapore need a cert to live anw all the best to them.

Shall post up two of their videos up for you guys to take a look enjoy =):
