The documents cite irreconcilable differences for the split and request that custody of their two daughters -- Eloisa, 11, and Maria, who turns three this week -- be granted to Miller with Huggins being granted visitation rights.

This is Miller's second marriage, as she wed Will Arnett in 1994. The couple divorced the following year.
