Chris Brown Promotes Ex-Girlfriend's Clothing Line

Karrueche, being the fame whore she is, decided to use our very own Breezy to promote her clothing line, which officially launches today, 12-12-12. Chris Brown has been a good sport, helping her promote the line all week. He has been posting pics of her collection on his instagram TL.

Wonder what RiRi has to say about all this.
