According to E! News, "Fox cited irreconcilable differences as the reason for their split. Additionally, she has requested joint legal and physical custody of their kids, along with termination of spousal support for her and Green."
Although this might seem like the end of their relationship, this is not the first time Fox has filed for divorce.
The actress also filed for divorce in August 2015 though the couple later got back together.
The pair of them have definitely had their share of ups and downs--and even the beginning of their relationship had its fair share of drama.
After meeting on the set of Hope & Faith in 2004, the couple dated for two years before announcing their engagement. However, in February 2009, they called off their engagement. At the time, a source told People that the decision was "mutual." By June 2010, they were back together--and confirmed that they still planned on marrying. A few days later, they were married in a secret ceremony in Hawaii.
With their rocky past in mind, the news of their divorce might not mean a complete end to their relationship; it certainly hasn't in the past.
However, that was before Fox met MGK, who she has dubbed her "twin flame."
A source told E! in October that Fox and MGK are "very serious" and that they are "planning their future together."
The insider added, "They see themselves as soulmates and life partners. They are taking steps every day to build on that. Machine Gun Kelly has met her kids and is becoming a part of their lives. She wanted to make sure it was going in a serious direction and they both feel very strongly that it is."
Fox's filing for divorce definitely sounds like a necessary step in becoming "life partners."
