Both Katy Perry and Lady Gaga had their singles hacked over the weekend.

And the leak comes as a heavy blow to the music stars.

Lady Gaga tweeted on Saturday that "her people were on the case," after Applause went on line unexpectedly.

Gaga's tweet started with a mix of religion and foul language, :Lord, in HEAVEN WHY YOU JUST COULDNT WAIT THIS IS TOO MUCH FOR ONE SATURDAY, adding, Now its not that we HATE computer speakers its just they're not as HQ. We spent time actually making sure it sounds good in #### speakers," mtv reported.

She added, "Don't worry. THE HAUS BUREAU is on the case. -TechHaus.

She also sent a tweet to Katy Perry about getting together to "#### up some hackers."

At this point, Gaga's anger inflamed spotlighting on curses and leaving out the religious insinuations, "Wanna grab some shovels and #### up some hackers? @katyperry."

Sounds like a logical question since Roar refers to Katy Perry's debut single, which was slated for debut on the album Prism. The leak comes two ahead of the release by Katy's EMI/Capitol label. Apparently, the record company released the single to radio stations.

Responding to Lady Gaga's hacker bashing, Katy Perry said she was more interested in making a hoopla about her brother's birthday.

"HEY! I know how you guys can make me feel better about the leak...Get #HAPPYBIRTHDAYDAVID trending for my lil bro's 25th today! @sirdavidD," tweed Katy.
