Levin might be gay but do not, repeat, DO NOT believe ANYTHING you read on Wiki.
This stuff is WRONG all the time.
That EXACT same line you posted “is openly gay and lives in Los Angeles with his long-time partner, a chiropractor.” was not too long ago also listed for former NFL monster Warren Sapp, and Sapp is NOT gay.
Wiki is FULL of lies.
Levin has talked about it on TV.
