AceShowbiz - Megan Fox's new family dynamic may be a challenge for Machine Gun Kelly. According to a new report, the "Bloody Valentine" rapper, who is currently expecting his first child with the actress, may not have the best relationship with her ex-husband Brian Austin Green.

Source close to the situation reveal to TMZ that the musician and the 'Beverly Hills, 90210" alum don't have any relationship. That could potentially lead to a drama between the two after Megan and MGK's child is born.

The "Transformers" star and Brian, who were married to each other from 2010 to 2021, share three sons, Noah, Bodhi and Journey together. Brian also shares a son named Zane with his fiancee Sharna Burgess.

Recently, it was reported that Brian had nothing but best wishes for Megan and MGK. "Brian knows how great of a mother she is and has been for their children," the source explained. "He doesn't imagine that will change in any way as she welcomes a new child with Colson," referring to the rocker, whose real name is Colson Baker.

"He wants everyone to be healthy and Brian will welcome her new child into the world when it happens with no drama," the source added. "Brian is not going to make this wonderful moment in their life a time to bruise his ego. He is OK with it and was made aware of it before the world found out. Brian's cool with it."

Sharna also took to her Instagram account to publicly congratulate the expecting mom. The former "Dancing with the Stars" pro shared Megan's maternity photo on her Instagram Stories. "Welcome little one, we are all so excited to meet you [heart emoji] Congratulations Mama x," so the performer wrote.
