As part of American Idol's first night of viewer-decided eliminations, it was officially announced that both Jennifer Lopez and Gwen Stefani will be performing on the show later this season. Also slated for stop-bys are Jon Bon Jovi, Martina McBride (one of my favorite tennis players), Diana Ross (maybe that fueled the Jacko rumor?), Barry Gibb, and Lulu and Peter Noone from Herman's Hermits (fronting a "British Invasion" theme night. Start shuddering now).

In other Idol news, Season 5 finalist Kellie Pickler will perform her new single, "I Wonder," on next week's results show.
