According to the latest TomKat story floating around, the couple had been "arguing about Suri's indoctrination into Scientology" and the whole Sea Org bit was the breaking point for Holmes.
But, was the six-year-old style maven really going to be forced to join the strict religious group?
This one is...
In response to reports involving Suri joining the Sea Organization, Gary Soter, who represents the Church of Scientology, International, tells E!:
"With regard to your question about Suri Cruise joining the Sea Organization, Scientology's religious order: The first we've heard of this is from the media. The story is preposterous and untrue."
A lawyer for the church later told TMZ no one under the age of 16 can join the Sea Organization, and that without exception all minors must have the "consent of both parents and/or all legal guardians" in order to join.
In case you haven't heard of the Sea Organization before, it is an elite Scientology group reserved for the "singularly most dedicated" of the religious order, according to the Washington Post.
And its members are required to sign a "one-billion-year-pledge" to serve the religion.
