He has since moved on with Sharna Burgess; they share a son together named Zane, born in June 2022.

Machine is referring to Brian slamming him in February.

Last month, Brian took to his Instagram stories to call out Machine, writing: ‘Bro. Just be honest for once in your life. ‘Stop caring so much about how you’re perceived that you will try and drag other people.’ 

Brian attached Kelly’s track, Don’t Let Me Go, to his social media post. 

The reason why former Beverly Hills 90210 star wrote the message on his Instagram stories was because Machine questioned the narrative that surrounded his relationship with Megan. 

Machine shared pictures of himself on January 28th looking outside a window and off the camera – while shirtless.

He wrote as the caption: ‘How can “sources say” when the sources haven’t said anything.’ 

In December, Brian expressed regret that Megan is navigating her latest pregnancy while dealing with the fallout from her break-up.

He was asked about his thoughts on her split from Machine, telling TMZ: ‘I didn’t even know.’

The cameraperson then proceeded to tell him about the text messages Megan reportedly found in November that led to her calling it quits with Machine. 

Adding: ‘How old is he? … He’s in his 30s, isn’t he? … But in your 30s, like, f**k. Grow up. Like, she’s pregnant.’ 

‘I just want the best for her. I want the best for the baby. I want the best for our kids. That’s a shame,’ he said to TMZ. ‘I’m heartbroken about it because I know she’s been so excited. And the kids are so excited for life and the change and all of that.’

Brian called the situation ‘tragic’ and noted that he does not know ‘the facts.’ 

Megan pulled the plug on her relationship with Machine over Thanksgiving- after reportedly discovering he was speaking to other women behind her back. 

Megan is currently pregnant with her and Machine Gun Kelly’s first baby together – which she had announced in November. 

Their five-year romance came to an end over Thanksgiving weekend while they were on holiday in Vail, Colorado, according to TMZ.

Machine Gun Kelly, born Colson Baker, left the trip earlier and they have not seen each other since.

The star is determined to focus on her unborn baby, rather than drama in her love life.

The insider told People: ‘They tried to make things work for many years. It was exhausting for Megan.

‘She’s done with him now. She just wants to focus on the baby and her boys now.’

Megan ‘doesn’t have much contact’ with the ‘Wild Boy’ hitmaker, even though they’re expecting a child together.

She posted a picture of her with her pregnant belly and a snap of her positive pregnancy test – to one of Machine Gun Kelly’s songs in the pregnancy reveal, which she shared on November 11. 

She is reportedly due in March. 

The song of his that she chose was Last November, which refers to the miscarriage she had suffered with the musician previously.

Megan captioned the post: ‘Nothing is ever really lost. Welcome back,’ adding a heart emoji.

They got engaged in January 2022 with the couple briefly splitting in February 2023 but working things through and getting back together – but not getting engaged again.

Megan previously revealed she believes she manifested the rapper turned rocker into the person he is, adding that she manifested him when she was four years old.

‘He’s literally my exact type that I’ve been manifesting since I was four. I’m also four years older than him. So, I think I made him.’

Adding: ‘My thoughts and intentions grew him into the person that he is, who knows what he would’ve looked like or been like if it wasn’t for me.’

The couple met on the film project Midnight In The Switchgrᴀss in March 2020.
