Jaime King's Husband Austin Sosa Files For Divorce

Jamie King Tells TMZ ... “I was completely blindsided by the divorce filing, which came out of nowhere. I was with Austin the night before it became public, and while like many marriages we had normal challenges, I genuinely believed we were working on our relationship. Any recent interactions being referenced publicly were strictly professional business meetings and have no connection to this private matter. My focus right now is my work and, above all, my children. This is deeply personal and should remain private, and I hope people will stop making assumptions— particularly ones that unfairly and disproportionately scrutinize women simply for doing their jobs.”

Jaime King's second husband, banker Austin Sosa, is withdrawing from their marriage ... because he just filed for divorce.

Austin beelined it to court Thursday and filed to divorce Jaime ... according to online records.

The reason for the split is unclear ... but the divorce filing comes just weeks after there were reports linking Jaime to another man, hotel owner Vikram Chatwal.

For her part, Jaime reportedly denied she was seeing Vikram, insisting their hangouts in Los Angeles were all business ... but that didn't stop Austin from pulling the plug.

Seems Jaime and Austin got married in a secret wedding ... no one even knew they were hitched ... back in July, reports emerged that Jaime and Austin were engaged.

No word on a date of marriage or date of separation because the divorce docs are not available yet ... we're working on it.

Jaime and Austin did NOT have any kids together ... so no child custody or support issues to hash out here.
