After showing off "this weird claw hand" she does when she's excited, Bibb talked about what happened the time she saw Meryl Streep.
She was sitting with her agent when she spotted the screen legend. Bibb's visceral reaction was, "I just want to go punch her out! ... She's soooo cute!"
Cooler heads prevailed, however, as Bibb's agent advised her to steer clear of Streep.
And it was just as well -- reliving the moment, Bibb realized that "I kind of wanted to eat her! ... Her little cheeks! She's so cute!"
However, "Smash" star Anjelica Huston wasn't as lucky as Streep. Bibb actually went up to Huston and, carried away in the heat of the moment, said, "You're so beautiful I want to cut your face!"
Bibb's fellow guest, Ed Helms, then chimed in, joking that he loves Robert De Niro so much he'd punch him.
