Singer Mariah Carey's account was hacked on New Year’s Eve.
Carey’s account tweeted dozens of off-the-wall and offensive statements including racial slurs before Twitter locked it.
Twitter confirmed that Carey's account had been compromised.
"As soon as we were made aware of the issue, we locked the compromised account and are currently investigating the situation," the company said in a statement sent to USA TODAY Tuesday.
The hackers claimed to be The Chuckling Squad that in August broke into the Twitter account of Twitter CEO Jack’s Dorsey as well as other celebrities.
At least one arrest was made in the hacking of Dorsey’s Twitter account, according to Motherboard. The hackers used a technique called SIM-swapping, where hackers trick a wireless provider into handing over control of a phone number.
