Miley Cyrus' biggest career accomplishment isn't Hannah Montana.
It's a cameo she shot in the upcoming Sex and the City 2.
"It was the best job I've ever done," the singer, 16, said on Ryan Seacrest's KIIS-FM radio show Friday. "It was a total dream come true."
She filmed her scene Oct. 17 at NYC's famed Ziegfeld Theater. She wore the same dress as Samantha Jones (Kim Cattrall) at what appeared to be a movie premiere for Samantha's on-and-off beau, Smith Jerrod (Jason Lewis).
"I didn't end up shooting until 11 p.m.," Cyrus said. "It was awesome — I got a free trip to New York. I hung out in New York all day and then I got to go to the set. I literally shot for an hour-and-a-half, and it was done."
Cyrus said "working with Kim was really cool. Sarah Jessica Parker was the nicest person in the world."
