Un-congratulations to Lifetime TV. You’ve created the train wreck-iest reality show yet: “The Houstons: On Our Own” (Wednesdays, 9 p.m.).

The show stars the daughter and relatives of late superstar singer Whitney Houston. They really do say, “Houston, we got a problem.” And the problem is Whitney’s 19-year-old daughter, Bobbi Kristina, above.

Mumbling and making faces, “Krissy” often seems in a drunken haze. She has delusions of a showbiz career. She blows off family events because “I’m tired.” She says she’s “engaged” to Nick, who was unofficially adopted by Whitney. No one in the family trusts Nick. Says Nick: “What most people don’t understand about Krissy and I’s relationship is we stand each other up.”

Aunt Pat declares: “I don’t want [Krissy] dealing with her mother’s passing in the wrong way.” (And the right way would be allowing cameras to film the family so Aunt Pat and company can have their 15 minutes of fame?)

Nathan Lane once joked that if you look up “dysfunctional” in the dictionary, you’d see a picture of his family. Sorry, Nathan, the Houstons have got you beat.
