Naya Rivera Files For Divorce


Naya Rivera's surprise marriage to Ryan Dorsey has fallen apart ... according to new court docs.

Naya filed for divorce last week, and -- according to her lawyer -- she's asking for primary physical custody of their 1-year-old son, Josey, with visitation rights for Ryan. The couple was married for a little more than 2 years. 

You'll recall ... Big Sean said he broke off his engagement to the former "Glee" star back in the spring of 2014 after accusing her of being too controlling. Just a few months later, Naya was married to her longtime actor pal, Ryan -- seemingly out of nowhere. 

Somewhere out there ... Big Sean is smiling. Probably.
