Megan Fox welcomed her fourth baby on Thursday

Vibrations produced by 432 Hz music are thought to have a soothing effect on the nervous system, decrease physical discomfort and relax muscle tension.

The actress already shares three sons Noah, 12, Bodhi, 11, and Journey, 8, with ex-husband Brian Austin Green.

Meanwhile, Kelly, welcomed his only other child, Casie, with Emma Cannon in July 2009.

The announcement comes just hours after Kelly blasted Green in a shock direct message on Instagram.

Brian, 51, posted the message from Machine to his Instagram stories Thursday morning – along with his thoughts on it.

Fox and Kelly, 34, split in November after she reportedly discovered he was speaking to other women behind her back. It is unknown if Megan has already given birth.

Machine’s direct Instagram message to Brian said: ‘Stop asking when our child is gonna be born. you the FEDS,’ adding a rat emoji and a police officer emoji.

‘Quit calling TMZ and focus on that apology you owe me for speaking on my name in public, Machine continued. ‘You chose the wrong one to f*** with mr child actor. Go back to cereal commercials.’

The announcement comes just hours after Kelly blasted Green in a shock direct message on Instagram

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.

They split after Megan ‘found material on MGK’s phone that was upsetting, and it made her want him to leave the trip early,’ the source said.

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

An insider recently claimed that Megan wanted to just ‘focus’ on her pregnancy.
