Coming back, the hosts remind us about the whole Pepsi endorsement that's totally even better than the $5 million contract. Carly is reintroduced, with more promises for a huge surprise, which the hashtag on the screen reading #DivasDuet may or may not be a clue about. Carly begins singing "How Do I Live" and then stops so she can introduce LeeAnn Rimes. Well, I would have been surprised. As it is, we just have to be surprised at how very alarming the former teen star looks these days. Behold your future, Carly Rose Sonenclar. After they do their best to out-belt each other while pretending to enjoy themselves, the hosts come out and let them gush about how amazing it was for both of them. Britney gets to declare them "shockingly amazing," and that's all the judges' remarks for that performance. So does it not count then?
For Tate's second performance, L.A. mentions another special guest and the hashtag is #TateTown. Sounds like a major downgrade from Tate Nation, unless you're aware that the song he's singing, "Pontoon," is by the country foursome Little Big Town, who come out and join him for the second verse. Ever done a duet with a four-piece band? Don't. Tate shouldn't have. It's so awkward that he actually looks uncomfortable on this stage for the first time ever. Or maybe I'm just projecting. L.A. however, lies that Tate seemed right at home. I thought he just looked like he was wishing he was there instead of here.
There's another plug for the 2013 auditions and then Simon reintroduces Fifth Harmony "with a very, very good friend of mine." And then the group starts singing "Give Your Heart a Break" again over the hashtag "Sixth Harmony," which is less of a clue to their celebrity duet partner than the long-distance shot of the stage revealing that Demi's chair is more vacant than usual. And since she's the one who originally recorded this song, I don't know why Camilla's mid-song intro of her is so overwhelmed and emotional and even disbelieving at the honor being bestowed upon her and her bandmates. But there's Demi singing with them, looking a little out of place in her work clothes and all. Simon loved it though, and he pops up for the standing ovation faster than I've ever seen him do on this show. Afterward, Demi tells the hosts that it was "so much fun" and the group says it was "amazing." Even Simon acts pained to tell Demi she was sensational and even invites her to join the group. And I thought the Tate Stevens thing was embarrassing.
