The cyber criminal accessed the "Dreamgirls" star's page and began sending out a number of odd tweets.
It appeared Hudson had regained access to her account, but it was reportedly the hacker sending out messages to make it seem like the 34-year-old was back in control.
Members of Hudson's team were alerted to the problem and began posting messages informing fans they were working to resolve the issue, and it now appears the star has regained access to her account.
"Hey #TeamJhud I think I'm back," she writes.
