"Game Of Thrones'" Cersei Lannister, or Lena Headey in real life, shared drinks and exchanged insults with TV show host Jimmy Kimmel last Monday night.

In The Jimmy Kimmel Live's Youtube video, the host revealed the his obsession with the HBO series. He was so taken with Cersei's character that he thought of doing an unusual interview with actress.

The famous actress gamely accepted Kimmel's invitation to talk to each "Game Of Thrones style" despite not wearing Cersei's trademark blond hair and Westeros wardrobe.

"No one drinks a goblet of wine like you do on 'Game of Thrones,'" Kimmel told the actress before starting the hilarious banter.

Bringing real goblets and some wine out, the pair began their insult war. The studio even dimmed the lights and put on some appropriate background music.

In her Cersei Lannister character, Headey started with, "That's a lovely tie. It's such a shame it's around a worthless neck."

Kimmel countered the jab with his own veiled insult of Heady's onscreen incestuous relationship with her brother, Jamie Lannister.

"So, you host a television program, how fun," she jabbed back, "You should enjoy it while it lasts."

At one point, Kimmel told the "Game Of Thrones" star, "You know, you're so good on the show. Is it a challenge to play Cersei or [do] you just naturally suck the life out of every room you enter?"

"You have such a way with words," she replied, "I wonder if you'll be as clever when I have your tongue ripped from your throat."

Kimmel held his own while calmly sipping his wine in between jabs. Being the clever Cersei Lannister however, Heady won the diss battle with her witty comebacks.

The defeated host conceded with a toast. "Nicely done," He told Heady, "You are the master!"
