So who are we talking about? Why, none other than Kristen Stewart, Taylor Lautner, and Josh Hutcherson! Taylor and Josh together in the same building? That might just be hotness overload!

Other big-time stars who are confirmed to be making appearances at the awards tomorrow include Emma Stone and Andrew Garfield, Katy Perry, Taylor Swift (who is getting a humanitarian award from Michelle Obama!), Zac Efron, Selena Gomez, and many, many more! Plus, Will Smith is hosting, so you know it's going to be a great show!

As for the other Twilight and Hunger Games peeps, we know that Liam Hemsworth won't be able to make it because he'll be in Las Vegas for the Academy of Country Music Awards (where he'll acutally be presenting an award!), but we're still waiting to hear either way about Jennifer Lawrence and Robert Pattinson. Maybe Rob will make a last-minute decision to accompany his girlfriend Kristen to the awards? Guess we'll have to tune in to find out!

The Kids' Choice Awards will air live on Nickelodeon Saturday night at 8 p.m. EST!

Who are you looking forward to seeing more -- Josh or Taylor?
