Swift confirmed the hack via Tumblr and said that Twitter is actively working to shut down the attackers.
"My Twitter got hacked but don’t worry, Twitter is deleting the hacker tweets and locking my account until they can figure out how this happened and get me new passwords," Swift (or a member of her team) wrote. "Never a dull moment."
