Megan Fox let Machine Gun Kelly meet her three kids from estranged husband Brian Austin Green

Their relationship seems to get more serious by the day.

And Megan Fox reportedly let her new boyfriend, Machine Gun Kelly, meet her three children from estranged husband Brian Austin Green, according to PEOPLE magazine.

Megan, 34, and Machine, 30, ‘spend as much time together as they can’ and they’re ‘planning a future together’ after dating for just a few short months.

A source told the publication: ‘He recently met her kids for the first time. Megan thought it was a natural step, since they are getting more serious.’

Megan shares three kids with her estranged partner: Noah Shannon, seven; Bodhi Ransom, six; and Journey River, three. 

Green, 47, confirmed their split earlier this year after nearly 10 years of marriage. 

‘They are in a committed relationship and it’s not just a fling,’ an insider added. ‘They are planning a future together.’ 

Kelly — who’s real name is Richard Colson Baker — has a 12-year-old daughter from a previous relationship named Casie. 

Megan and Kelly went public with their new relationship in May after meeting on the set of the movie Midnight In The Switchgrass. 

During an interview on Lala Kent’s podcast, Megan said she ‘knew right away that he was what I call a twin flame.’

She added: ‘Instead of a soul mate, a twin flame is actually where a soul has ascended into a high enough level that it can be split into two different bodies at the same time. So we’re actually two halves of the same soul, I think.’

Randall Emmett’s directorial debut was being filmed in Puerto Rico before production shut down in March due to the COVID-19 pandemic.

The crime thriller also stars Bruce Willis, Emile Hirsch, Lukas Haas, Sistine Stallone and Michael Beach.
