Machine Gun Kelly responded to a recent comment about relationship advice from Megan Fox with just one word.

A recent video posted to Instagram had her talking a bit about relationships, and MGK, real name Colson Baker, added his response to the mix.

In the video, which Fox captioned ‘life advice from a relationship expert’ she was asked by The Rundown’s host, Erin Lim Rhodes, what she’d say to those in the audience having a ‘single summer’.

So, what does the Fox have to say to that?

She said: “I don’t know if I’m the best person to give advice, because my advice is like ‘just learn a skill or develop a hobby, and do not waste your energy on boys’.

“All they’re gonna do is drain you. Just move on, invest in yourself.”

Posting this snippet of the interview to Instagram, it naturally got the massive wave of reactions that a major celebrity is going to receive.

Kim Kardashian added: ‘Not no’ and a bunch of people tried to work out what on earth that was supposed to mean.

However, one of those reactions reportedly came from Machine Gun Kelly himself.

His response was to comment the singular word ‘PREACH’ – though it appears that he has since deleted that comment.

And if you thinking there might be beef between Fox and Kelly then you maybe want to think again, as Fox said that he was one of her ideal headliners for Coachella.

“Well, obviously, I have to say Machine Gun Kelly,” she said when called on to name three performers she’d want to see.

“I’m not in the modern era, so I would say, Guns N’ Roses or, you know who I would love to see, is Weezer. Weezer’s so fire.”

You might be wondering just what the hell is going on between those two but that’s for them to figure out, as after Fox confirmed their engagement had been called off, she said their relationship was ‘not for public consumption’.

The actor acknowledged to Alex Cooper that people would find what was going on ‘confusing or interesting’ and want to know more.

She said: “I refer to as being my ‘twin soul’ and there will always be a tether to him, no matter what.”

“I can’t say for sure what the capacity will be, but I will always be connected to him somehow. Beyond that, I’m not willing to explain.”

Whatever happens next between them, or perhaps doesn’t happen, appears to be a matter for them to deal with.

Best of luck to them, and here’s hoping the folks set for a ‘single summer’ get to enjoy it.
