Jaime King is officially back on the market … after a judge signed off on her divorce from her now-former husband, Austin Sosa.

According to court docs, obtained by TMZ … a Los Angeles County Superior Court judge entered the final judgment on Friday.

The court docs show that both parties are now restored to their status as single people … but jurisdiction was reserved on the issue of spousal support for King.

We reported earlier … Austin wanted to push the divorce case along and asked the court to end the marriage by default in July.

Jaime — who was previously married to producer Kyle Newman — responded to Austin filing for divorce in January of this year, saying she was “completely blindsided.”
