Machine Gun Kelly snorts white powder off Megan Fox’s breast during Halloween

Machine Gun Kelly (MGK) has set tongues wagging after he got a little too into character this Halloween.

The 32-year-old rapper and his girlfriend Megan Fox dressed up as Tommy Lee and Pamela Anderson for the spooky season's big night of nights with props including of a substance that appeared cocaine.

MGK uploaded a picture of himself and Fox alongside a picture of Pam and Tommy for comparison - they were spot on, by the way - and a video of the singer snorting a line off of Fox's ample bosom.

People on social media wasted no time in rinsing MGK for the post, accusing him of glorifying drug use.

One person said: "Even if it's fake, and a joke. This is not okay to promote to your fans and it's even worse for the children they both have. Highly disappointed, really not a fan of you anymore at this point."

Another added: "As a person that is two years sober this is absolutely disgusting and disrespectful. Just lost me as a fan and probably a million other people in recovery that used to idolise you."

A third simply stated: "This is not the flex you think it is."

Some, however, took the clip as a joke and labelled the celeb couple as 'iconic' and 'epic'.

One person said: "Ha, this is next level."

Another added: "Oh my God, dude you made me laugh so freaking hard."

The chaotic couple also came under fire for their choice of Halloween costumes with internet users accusing them of glorifying and romanticising a 'toxic relationship'.

Some fans responded to the images to say Fox and Kelly 'nailed' the costumes, but many other internet users have criticised the 'couples costume' idea and argued that a 'toxic relationship' should not be taken lightly.

One Twitter user described the costumes as 'disgusting and deranged', while another commented: "Why are loads of couples dressing up as them? It was an abusive relationship."

They even mimicked the famous couple's iconic photo shoot poses from years ago, posting a few snaps to Instagram.

Fox appeared to be wearing the exact same pink and red latex dress once worn by the iconic Baywatch star, while MGK chucked on a pair of leather pants and a white singlet to complete the look for the Casamigos Halloween party in Hollywood.

Sharing their snaps, Fox wrote: "But are these even costumes?"

LADbible has attempted to reach out to a representative for Fox and Kelly for comment.
