EDIT: The show has not been canceled!

TVGuide reports a press release from NBC,
"I think there are alternatives we may look into. It's all a conversation for the fall."
This means they are giving Lipstick a chance in Spring. But when Fall comes in, they'll look at the numbers again. There's hope for the show yet!
So the studios will most likely air them until the winter break (if they have enough episodes to). And then they'll replace the shows with something else. Pretty sure "canceled" means NBC has chosen NOT TO order any more episodes for either shows.
They do that a lot these days, ordering only a few episodes or half a season. Then if the show does well they'll give the go-ahead for more eppys.
