Having just celebrated the launch of her new album, Echo, Leona Lewis made her way over to the Us Weekly Hot Hollywood 2009 Party to get her due for Chanteuse of the Year. Fellow reality TV singer, Adam Lambert was also recognized as Glam God of the Year and lived up to his title in his shiny pants, leather jacket, lots of jewelry and eyeliner.

Kristin Cavallari was given the title of Comeback of the Year and showed up the event looking skinny as hell. She was dressed in all black and as we know, that color has a slimming effect, and she’s already plenty thin as it is.

Of course, it was LaToya Jackson who stole the show, wearing a bright orange jacket that perfectly matched her nails. I’m glad to see that she didn’t let a little thing like an invitation stop her from having a good time!

The full list of honorees are after the jump.
