It was almost like seeing double when Miley Cyrus and her older sister, Brandi Cyrus, met on the red carpet at Sunday's American Music Awards.

• Working the carpet for Spin Media, the two sisters shared a moment when Brandi, resembling the more sophisticated Miley of not too long ago, interviewed her younger sister.

"I got to talk to a lot of amazing people tonight BUT I had the MOST fun chatting with my little sister!" Brandi tweeted after the show.

"She looked gorgeous and ended up blowing everyone away when she closed the show with her performance of "Wrecking Ball". How cute was that cat? MEOW!" Brandi wrote.

Brandi made quite the impression herself. Wearing in a white mini dress and black and white strappy high heels, she was asked to pose on the carpet by photographers who recognized the family resemblance.

Though Brandi, 26, has stepped out with her more famous younger sis in the past, the older Cyrus sib is clearly making a name for herself.
