It seems that she had won her ticket to attend the Grammy's from Star (broadcast, not print). They then wrote to the Grammy's to ask that she be allowed to walk down the red carpet with all the other international celebrities. The Grammy's gave her the green light.
In a way, this is more of a recognition for her as an international artiste. She is will also be able to rub shoulders with some other international celebrities. I do hope that she brushes up on her English though. The last I'd heard, she doesn't speak 'the English' too well.
As usual, she will be dressed spectacularly. She's gotten Bernard Chandran to make her a new dress. No details are out yet except that it'll be a black-white dress with plenty of Malaysian motives, probably a nice kebaya I guess.
I don't actually see a reason why she cannot be marketed worldwide except for the fact that her record label doesn't wish to do it. The language shouldn't be a barrier, and neither should the music. The problem is probably her insistence on being prim-and-proper. That image would probably be fairly difficult to sell outside of a few countries.
And just for the heck of it, I'll link a youtube video of her "biarlah rahsia" MTV here. When I showed some of my foreign friends this video, they all said that she had a good voice, even though they didn't understand what the song was about at all. I like it. Hope that you do too.
