The New York Daily News reports that E! Online’s Twitter account was hacked Saturday. “Exclusive: Justin Bieber to E!online: I’m a gay,” the hackers posted on the E! Online account. Their provocative headline received 1,200 retweets and 351 favorites.

According to Mashable, the Syrian Electronic Army, a group of hackers who support al-Assad, claimed responsibility for the hack. The Daily News reports that this is the same group that was responsible for the April hijacking of The Associated Press Twitter feed.

In a statement shortly after the hack, E! Online said that its accounts were “compromised” and that they were working to resolve the situation “as quickly as possible.” The entertainment news organization also promised to investigate the incident.

Bieber wasn’t the only celebrity targeted by the SEA’s hack on E! Online’s Twitter account. The group also tweeted: “Angelina Jolie admits, in E! latest issue, that Jordan is to blame for the Syrian refugees’ atrocious conditions.”

Mashable noted at the time that it wouldn’t be a good idea to click on any links tweeted by @eonline until the situation was resolved, as they may take users to malware downloads or other corrupt sites.

In April, hackers posted the following message of The Associated Press Twitter feed: “Breaking: Two Explosions in the White House and Barack Obama is injured.” In response to the tweet, social media went wild and the Dow dropped nearly 143 points in a three-minute span from 1:07 p.m. ET to 1:10 p.m. ET. Shortly after the fake tweet, The AP took down its Twitter account and announced that it had been hacked.
