Melissa Gilbert filed for divorce from her hubby Bruce Boxleitner on Monday, Us Weekly confirms.

Gilbert, 47, was married to Boxleitner, 61, for 16 years. In March, the former Little House on the Prairie star confirmed to Us that the couple had split.

"We have loved each other for a very long time and we share four incredible sons together," Gilbert said in a statement. She and Boxleitner have a 15-year-old son together, Michael; Melissa also has a son named Dakota, 22, from her four-year marriage to Bo Brinkman. Boxleitner has two sons from his marriage to actress Kathryn Oglivy.

The duo will seek joint custody of Michael, and Gilbert seeks not to pay spousal support to Boxleitner.
