Heidi Klum 'Terrified' About Memorizing Lines For 'Parks & Recreation' Guest Spot (VIDEO)

Heidi Klum found time in her schedule to drop by "Late Night with Jimmy Fallon." While there, Fallon talked about another thing she squeezed into her schedule. Between her work on "America's Got Talent" and "Project Runway," Klum is making a guest appearance on "Parks & Recreation" for the upcoming season.

“I have to tell you, I was so nervous," Klum admitted of the guest spot. "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.”

Even now, she isn't sure how well it went. She did say that she was stunned to find out that Amy Poehler didn't know her lines either. This probably made her feel a little better, until she realized that Poehler memorizes her lines quickly in rehearsal and then is ready to go. Then, Klum was more nervous than ever!

Heidi Klum's guest appearance is on the season premiere of "Parks & Recreation," airing Thursday, September 26 at 8 p.m. ET on NBC. She plays a European mayor who's being honored alongside Poehler's Leslie Knope at a "Women in Government" event. Other celebs lined up for "Parks" this year include "Orphan Black" star Tatiana Maslany, Kristen Bell and Henry Winkler.

In the meantime, fans can enjoy Heidi Klum in her other gigs, appearing on "America's Got Talent" every Tuesday and Wednesday at 9 p.m. ET on NBC, and on "Project Runway" every Thursday at 9 p.m. ET on Lifetime. "Late Night with Jimmy Fallon" airs weeknights at 12:37 a.m. ET on NBC.
