"That '70s Show" star Wilmer Valderrama and Demi Lovato have been reported to have broken up in the aftermath of Wilmer's Twitter being hacked on July 3.

The cruel hacker dissed Demi, posting rude and disrespectful comments like calling her a "fat f*ckk." The hacker used a photo of the Powerpuff Girls, with the supposed "Demi" character towering over Miley, Ariana and Selena. He/She placed Demi's name on it with the caption: "She's fat as f*ckk."

To add more injury, the hacker also posted "supposedly" nude photos of Demi! Crazy!

After the incident, reports surfaced that the two had broken up. However, it seem this is so not true! The couple has been spotted together at the UFC 175 match in Las Vegas, Nevada, on July 5- evidently still very much together!

According to a source close to the couple, Demi and Wilmer is moving on from the cyber attack and that their relationship is "unbreakable".

"They were there and definitely together," the source tells HollywoodLife.com. "Everything was perfect with them, they just requested not to be photographed together."

"They watched the fights and they shared a lot of close cuddling PDA. They are unbreakable," the source reveals.

There were also rumors that Wilmer had knowledge about the attack or may have been part of it. "Wilmer was not part of the hack whatsoever, he would never do anything like that at all," the source says. "The two are in love and they aren't going to ruin it by posting something on Twitter so scandalous or reacting to it and making it a big deal."

On a different "Twitter" note, Demi has reportedly dropped Selena Gomez on Twitter and, as it seems, from real life. The Heart Attack hitmaker stopped following Selena on Twitter on Wednesday after posting a cryptic angry message, 'Swimming away from the bulls*** bye b**** (sic).' The post has long been deleted.

Demi, who has been friends with Selena since their Barney and Friends days also said in her tweet that she was fed up with all the "bullsh*t."
