• Lost: Shannon's coming back! E.W.'s Doc Jensen reports in this week's issue that Maggie Grace is now set to return for a guest appearance in season six. In other cast return news, reps for Andrea Gabriel confirm that Sayid's beloved Nadia is going to appear in season six as well. Gabriel first pops up again in the March 2 episode "Sundown," and then she also appears in a second episode to be revealed later. Last but not least, sneak peeks for next week's episode, "Lighthouse," include a look at feral Claire and an alt-timeline family Shephard.
• TV Fight Club? Our frienemy has posted a blind item about two rival thespians who maintain a deep animosity toward each other and who will be doing the same "small-screen opportunity" but not appearing onscreen together. Everybody and their mother seems to think the answer to the blind item is "Idina Menzel and Kristin Chenoweth," who costarred in Wicked and who both now have parts on Glee. Sad face. But maybe they'll prove the peanut gallery wrong by doing a Glee duet together later this season?
