Megan Fox and Machine Gun Kelly have chained themselves together by their nails

Machine Gun Kelly just launched his own nail polish brand for introverts

Machine Gun Kelly and Megan Fox have chained themselves together by their nails - which is probably the most mundane thing they have ever done when it comes to their relationship. The couple attended the launch party of Kelly's new nail polish brand UN/DN LAQR in California on Sunday night, their outfits and their nails matching one another.

"Party Favor," "25 to Life," and "Depressionist" were all used, in case you want to copy the notorious bad boy. "After the nails [were] dry, I used a nail piercer to pierce both of their pinky nails and added rings to them, so that I could attach two chains to them, so that they were chained together," she said.

As expected, the duo has hit the headlines worldwide and once again taken over Twitter. "What a fucking couple," wrote one fan. Another said: "If we aren't going to attach ourselves to each other by our pinky nails like Machine Gun Kelly and Megan Fox, then I don't want it." https://twitter.com/ticketstocolson/status/1467442585480445952 Machine Gun Kelly and Megan Fox are well known for pushing the boundaries of their love, with the former admitting last week that he once stabbed himself to impress his beau.

"You know how you throw it up, and you're supposed to catch it. I looked at her and I was like, 'check this out'." He added: "I was like, 'yo, I need stitches real quick.'"
