Weil, who stars in Shonda Rhimes’ show "How to Get Away With Murder," cited irreconcilable differences as the reason for the split, according to People. She and Adelstein -- who is best known for his work on "Scandal," "Private Practice" and "Grey's Anatomy" -- wed in October 2006.
According to court docs, the pair separated in January. Weil is requesting joint custody of their five-year-old daughter.
Weil is set to reprise her role as Paris in the upcoming "Gilmore Girls" revival on Netflix. Adelstein is currently appearing in Bravo's "Girlfriends' Guide To Divorce."
