Check out the new, short MV "Just One Lipstick" by 'Unpretty Rapstar 2' rappers Truedy, Heize and Kasper! No, it's not an official collaboration, but the girls put their skills together for makeup brand MAC's campaign for fighting against AIDS.

"Just One Lipstick" is a tight rap track and the fierce rappers are bright and bold in the MAC lip shades. If you didn't know already, you'll know now by listening to the song: December 1 marks World AIDS Day.

100% of proceeds from MAC's 'Viva Glam' lipsticks will go towards the campaign of changing prejudice against AIDS into hope for those with AIDS.

So this isn't just another rap track and MV, because Truedy, Heize and Kasper got together for a great cause.
