Adam Lambert's biggest supporter? Pal Audrina Patridge.
"For those of you avid American Idol fans, I just wanted to remind you guys to tune in tonight to vote at 9 p.m. on FOX!" The Hills star blogs.
"One of the contestants, Adam Lambert, is a close friend of mine and he's one of the most talented and sincere people I know -- he definitely has my vote :)" she continues.
Patridge, 23, posts a pic of her and Lambert, 26, mugging for the camera at his birthday party at West Hollywood's Chateau Marmont before signing off "xoxo, Audrina."
