Lena Headey has "Game of Thrones"-style spat with Jimmy Kimmel

Anyone familiar with "Game of Thrones" knows Cersei Lannister can cast a cold glare and a harsh insult like it's her job.

So when the actress who plays her, Lena Headey, stopped by "Jimmy Kimmel Live" on Monday it was no surprise that she was game to trade some "Thrones"-style barbs with the late-night host.

"No one drinks a goblet of wine like you do on 'Game of Thrones,'" Kimmel told her. "I thought it would be fun to talk to each other 'GoT' style."

Headey kicked things off with this snide opener: "That is a lovely's a shame it's around such a worthless neck."

Lots more wine-sipping and insult-throwing followed. Suffice to say, hers were more Lannister-worthy than Kimmel's.
