Last night in a dramatic results show, it was announced that La Toya London from Oakland, CA and Amy Adams from Bakersfield, CA were chosen by America to become the next two contestants to make the Top 12 on American Idol.

Approximately 13 million votes were received after Tuesday's performance show in which London captivated the audience with her performance of "All By Myself." Amy Adams had the audience grooving with her rendition of "Power of Love." Over 26 million viewers tuned in to Tuesday's performance show, which dominated the time period and was the highest-rated program of the night.

London and Adams were the two top vote-getters in their group and have advanced to the finals, joining Fantasia Barrino, Diana DeGarmo, Camile Velasco and Matt Rogers in the Top 12. The fourth set of eight semifinalists will perform on Tuesday, March 2 (8:00-9:00 PM ET/PT) on FOX. They will return to the stage the next night to find out their fate, as the results are revealed during the weekly live broadcast on Wednesday, March 3 (8:30-9:00 PM ET live/PT tape-delayed).

At the end of the March 2 episode, the phone lines will open and America can vote for their favorite contestant(s) via toll-free telephone lines until 11:00 PM ET/PT (10:00 PM CT/MT), subject to time zone restrictions. American Idol viewers who subscribe to AT&T Wireless may also use text messaging to vote by sending the word "vote" to the four-digit short numbers (5701, 5702 etc.) for the Idols of their choice. Each week, viewers will call or text one of the designated numbers -- each one corresponding to one of the performers -- to cast their vote.
