When news first broke out that Megan Fox and Brian Austin Green have separated, people got the impression that the marriage ended amicably. However, recent developments are showing that the relationship between the two is deteriorating.

Us Magazine quotes a source that says the relationship between Fox and Green after the end of their marriage has soured considerably, blaming Fox’s alleged unpredictable temperament. According to the source, it was this same attitude that caused the breakdown of their marriage in the first place.

The source also claims that Green’s feelings about Fox’s public relationship with musician Machine Gun Kelly have also been constantly changing. While the 47-year-old had supposedly come to terms with the relationship, it has recently become a sensitive topic for him again.

The deteriorating state of Fox’s and Green’s relationship may have been caused by Fox recently lashing out at Green on Instagram. Over Halloween weekend, Green had posted a photo of himself and his son Journey on his Instagram account. The action was not received well by Fox.

In the comments section of the post, Fox said that Green was participating in the narrative that she was not a good mother to her kids. She also said that she did not post her kids on her social media, even if she also had a fun time with them during Halloween.

GeoNews reports that Green had quickly tried to fix the situation by taking down the photo, especially since it apparently took some time before their relationship after their marriage got to a good place.

The source further added that Fox has long been averse to exposing her kids to paparazzi, which is why Green’s Instagram post angered her specifically. The move apparently set back the advances the pair have made when it comes to co-parenting their three children.

Fox and Green’s public spat is not the only one to have caught the attention of the press. Other relationships whose end was captured in the headlines include that of Ray J and Princess Love, Tracy Morgan and Megan Wollover, as well as Cassie Randolph and Colton Underwood.

Musician Ray J, for instance, grabbed attention when he filed for divorce from his wife, Princess Love. The divorce filing came two months after Love withdrew her own filing.

Morgan and Wollover, on the other hand, ended their five-year marriage last July. Morgan and Wollover were married after Morgan survived a car accident that would have left him either in a wheelchair or using a cane.

Randolph and Underwood only recently came to an understanding after their split resulted in Randolph asking for a temporary restraining order for Underwood, alleging that the former The Bachelor star was stalking her.
