Singer Taylor Swift’s Twitter account is back under her control after someone hacked into both her Twitter and Instagram accounts on Tuesday. According to Rolling Stone, Swift’s 51 million followers make hers the fourth largest account on Twitter and the security breach one of the biggest in Twitter’s history.

In return, Swift taunted the hackers with a parody of her hit “Shake It Off.”

Whoever hacked into Swift’s accounts did little more with the access than to take credit for the hacking and solicit followers; still, Swift couldn’t resist taking a swipe at those who claim to have nude photos.
