Katy Perry's Twitter account was hacked and the hackers posted some cheap and vulgar tweets, one referring to her feud with fellow singer Taylor Swift.
At around 12.30 pm, the songtress retweeted Hillary Clinton's Memorial Day message along with her message and an American flag emoji.
Five hours later, they wrote, "Miss you baby," while tagging the Shake It Off hitmaker's account. All of the tweets were deleted from singer's account 15 minutes after they were posted.
The official account later posted a screenshot of an e-mail from the music sharing site.
