Maybe one? Maybe both? Where's Alice when you need her?

Hold your horses. HitFix reports:

As HitFix confirmed exclusively, Robert Pattinson will be appearing on the telecast. Now, both of Hollywood's hottest under 25 stars? That's another matter entirely, but producer Larry Mark told E!Online there will be a presence "and on more than one occasion."

What does that mean? Both Robert and Kristen will appear at separate times, or Robert will appear more than once? Looks like it's gonna be a long night!
