ET was there as the stars of Sing dished on their animated characters at the Toronto International Film Festival.

Scarlett Johansson, Matthew McConaughey, Reese Witherspoon and Jennifer Hudson lend their voices to the musical comedy, and despite the heat, they glammed it up on the red carpet.

"'Warm in Toronto,' that's the name of this segment," Johansson told ET.

In the movie, a koala (McConaughey) enlists the help of his friends to host a singing competition, hoping to drum up business for his theater.

Johansson plays a punk rock porcupine, whose voice is bigger than her stature.

"I don't really know what she sounds like," Johansson said. "She's sort of just like loud and proud."

Witherspoon plays a pig, who beautifully belts out Katy Perry's "Firework" in the movie, but the actress told us that her singing at home isn't always welcomed by her three children, 17-year-old Ava, 12-year-old Deacon and 3-year-old Tennessee.

"I think I embarrass them terribly when I try to sing Drake songs," Witherspoon admitted with a laugh. "I don't stop singing. I enjoy it."

On the other hand, McConaughey enjoyed a status boost in the eyes of his three children, Levi, 8, Vida, 6, and Livingston, 3.

"I was hot stuff in the house for about three solid weeks after they saw this," McConaughey said. "There's a selfish reason behind doing these things."

Sing hits theaters Dec. 21.
