Margaret Cho -- Finally Pulls the Plug on Marriage

It took her nearly a year, but Margaret Cho has finally filed docs to legally separate from her husband after announcing they were splitting last December.

Cho announced last December that she and hubby Al Ridenour were splitting up, but she filed separation docs in L.A. on Wednesday. In the docs she says they've actually been separated since September, 2014.

Cho and Ridenour got married in 2003, and have no kids.

The comedian announced she was bisexual in 2013, and has also said she and Al had an open marriage.
