'American Idol': Allison Iraheta, Orianthi on 'So You Think You Can Dance'

"American Idol" Season 8 finalist Allison Iraheta graced the "So You Think You Can Dance" stage Thursday (July 29) to perform "Don't Waste the Pretty" during the live results show. Allison is currently on tour with fellow Season 8 finalist Adam Lambert -- in fact, her tour with Adam was just extended.

Allison was dressed in brilliant pinks, blues, and yellows. I loved the routine.

Besides reality shows, hip-hop battles, and ballroom dance competitions, I don't think of dance as competitive in that way. Results: Jose and Kent were up first. DROP THE AXE, SHOW.

Next up: AdeChike and Billy, the former dressed like a Dickensian street urchin. Finally, Lauren and Robert. Tony from Season 5?! The first guy eliminated that season? Man, this kid's voice sucks. Solos: Jose did lots of leg flairs and some tumbling. Musical guest 2: Allison Iraheta, with Orianthi, doing "Don't Waste the Pretty." Hm. Nigel talked about how Lauren's the only girl left because young female voters go for the cute young boys. As for Billy, he is technically a brilliant dancer, one of the most memorable dancers we've ever had on the show.
