The Born This Way singer took action after a number of mysterious Spanish tweets made their way onto her feed.
She posted: 'Whoever is hacking my Twitter must answer to 10 million monsters and Twitter police. #Don'tMakeMeCallTheApostles'
The messages appeared early this morning including links to Spanish YouTube-related sites, a mention of fellow pop diva Shakira, and a hashtag leading to a Spanish horoscope account.
Gaga's last post before her account was hacked was about her next video message: 'Gagavision no.44 coming 2morrow night, commemorating the last American MonsterBall. Hurts to write this. The stage is my home. #BornThisWay.'
The singer quickly deleted the tweets ten minutes later and reassured fans that it was back to business....
