Melissa Gilbert has filed for divorce from actor Bruce Boxleitner after 16 years of marriage. 
The divorce petition filed Monday in Los Angeles -- citing irreconcilable differences -- comes about five months after the Little House on the Prairie star and her husband publicly announced a separation.
Court papers show that Gilbert, 47, is seeking joint custody of the couple's 15-year-old son Michael. The filing states that Gilbert separated last January from Boxleitner, 61, who starred in last year's Tron: Legacy.
The news came just one day after it was reported that Melissa's sister Sara, 36 had split from her longtime partner, Allison Adler, 44, after a 10-year relationship. People magazine reported that Sara -- co host of The Talk -- will share custody with Adler of the couple's two children.
