Leslie's in London Town for the one hour premiere of "Parks And Recreation" this month, but she isn't alone: Heidi Klum is joining her!

In a new Season 6 promo (above), Klum's character -- a European mayor being honored at the same "Women In Government" event as Leslie (Amy Poehler) -- isn't exactly warm to Leslie when the two discuss the difficulties of politics.

Despite her character's confidence, Klum told Jimmy Fallon that the role was a daunting one to take on.

“I have to tell you, I was so nervous," Klum admitted. "There’s never a cue card, or prompter or lines that I have to memorize. And then, all of a sudden they gave me these pages and I was like, terrified.”

Tune in to the Season 6 premiere of "Parks and Recreation" on Thursday, Sept. 26 at 8 p.m. ET on NBC.
