NEW YORK (AP) — Miley Cyrus has quit Twitter, leaving her fans puzzled over her abrupt exit.

The teen pop star was one of the most popular people on the microblogging site, with more than 1.1 million followers. But the account for the 16-year-old Cyrus is no longer available.

In one of her last posts, she wrote that Liam Hemsworth, her co-star in the upcoming film "The Last Song," wanted her to delete her Twitter account "with good reason."

Publicists for Cyrus didn't immediately return requests for comment Thursday.

Fans of Cyrus have organized on Twitter under the heading "mileycomeback," which was one of the most popular topics on the site Thursday.
