Two words: sloth meltdown. Oh yes, KRISTEN BELL is here, and someone had to mention it! Known for her roles in "Veronica Mars," "Get Him to the Greek" and "Gossip Girl," the actress and new mom returns to Ellen to talk about her latest project, the icicle-y animated menagerie that is Disney's "Frozen." The film is being called the studio's best musical since "Beauty and the Beast," and what's more exciting than a winter wonderland, funny reindeer, talking snowmen, mystical trolls, and not one but two princesses?! As always, the starlet brings surprises, passion, and great stories about the movie, her new baby, hubby and ongoing sloth infatuation. Happy tears to come. All talk of ice will soon melt away when JASON MRAZ AND TRAVIE MCCOY take the stage. With McCoy's track "Rough Water" blowing up the charts, the Gym Class Heroes frontman puts the tinge of soul into his already eclectic vibrato by bringing the soulful singer-songwriter Mraz into the mix. The new single marks McCoy's first solo work since his hit "Billionaire" in 2010, and adds to a growing repertoire that includes records like "Stereo Hearts" and "Cupid's Chokehold." Mraz, a veteran in his own right, conquered the international ranks with hits like "The Remedy (I Won't Worry)" and "I'm Yours." Together, the dynamic duo generates a blend all of their own, and are a magnetic force to enliven Ellen's stage! Plus, it ain't "No Lie," 2 CHAINZ will be holding down the 1s and 2s as Ellen's guest DJ. "U.O.E.N.O."* (*you don't even know) how it's going to pop! On Tuesday, Ellen gets icy hot!
