During a November 9 episode of The Kardashians, Kardashian urged Appleton to get a prenup when talking about their upcoming nuptials.
"Wait, you have to get a prenup. Can I mention that in front of him?" Kardashian asked before belting out one of her ex-husband's most famous lyrics. "I don't care what you have, who you are, what you do -- We want prenup. We want prenup."
It was then that Appleton FaceTimed Gage so that the pair could ask Kardashian a very important question.
"Oh my God," Kardashian gushed. "Congratulations. Wait, can I just give you one tip from a lawyer: prenup."
As for the reason for the split, a source close to the couple tells TMZ this was not an easy decision for Appleton, 40, to make, but he tried everything he could to make the marriage work and needed to make the best decision for himself moving forward.
The couple's romance was a whirlwind, first going public with their relationship in February during a trip to Mexico, only to get engaged just a few weeks before their Vegas wedding.
Neither Appleton nor Gage has publicly commented on the divorce.
