We're told Armstrong cited "irreconcilable differences" as the reason for divorcing Russell Armstrong, her husband of nearly 6 years.
The couple have a 5 year old child. We're told Taylor will ask for joint legal and primary physical custody.
She will also ask for spousal and child support and there is no prenup
UPDATE:
Taylor was adamant about hiding what she has called a physically and emotionally abusive marriage.
And, sources say, Russell even got "aggressive" with Taylor at an event, and execs from Bravo witnessed it.
Taylor told People.com, her arguments with her husband often got physical with Russell grabbing her, shoving her, and pulling her hair.
Russell has denied the hair-pulling, but admits to pushing her blaming "Housewives" for pushing the couple to their "limit."
