Kristen Bell visits "The Talk" Thursday and dishes on "Frozen 2." On sharing new songs and plot line with her daughters, Bell says, "I'm in trouble because I did not have them sign an NDA... We worked on this movie for so long, we've worked on it for over two and a half years. So, I come home and I learn a new song, and I sing it to them at night in bed. And then, I would like tell them new story plots, and then I realized, on my God, I really need to be careful." She adds, "The problem is, they're terrible secret keepers, so I really got myself into a pickIe." Bell spills on new songs for the film, "Yes, well we tease something that Idina [Menzel] sings called 'Into The Unknown,' which is a breathtaking song... I have a song, it doesn't hit those high notes because I'm of the opinion, if you have Lebron James on your team, you don't try to dunk... I do more emotional comedy stuff, and then Idina's got two songs that are just going to blow people's minds."
