Texas-accented First Twin Jenna Bush appeared on Larry King Live last night to plug her new book Ana's Story... and she was both kinda charming and completely sober. In addition to discussing the AIDS epidemic in Third World countries (which, uh, her dad isn't exactly helping to alleviate!) Jenna seemed more than happy to talk about her engagement to Henry Hager and show off her not-as-ginormous-as-we-thought sapphire-and-diamond engagement ring. Jenna wouldn't say — or honestly doesn't know — whether she'll be having a White House wedding. But we're hoping to God she says "I don't".
