Mariah Carey is the latest celebrity to suffer a social media hack, as fans noticed the singer’s Twitter account spewing racial slurs on New Year’s Eve.

For nearly half an hour, Carey’s account posted several unexplained links, along with slurs — including the n-word — and references to her ongoing feud with Eminem.

Once hackers lost control of the account, the tweets were deleted, leaving Carey’s 21 million followers scratching their heads.

The posts claimed to be from the “Chuckling Squad,” a hacker group that seized control of Chloë Grace Moretz and Twitter CEO Jack Dorsey‘s account this past summer. The common thread linking those attacks was cell carrier AT&T; it’s unclear who provides Carey’s cell phone service.
