It's the question of the moment: are they or aren't they?

Have 'Twilight' stars Kristen Stewart and Robert Pattinson confirmed that they are indeed a couple before a taping of an Oprah Winfrey show?

Depending on which version of the story making the rounds on the Internet the pair - or their personal publicists from 'Twilight' - confessed all to the chat-show queen herself or to her aides.

In exchange, Winfrey promised to go easy on the dating question while on the air.

Fans at the taping confirmed that the TV host said at one point, 'Everyone wants to know ...' which led to Pattinson joking that Stewart was pregnant and the actress countering by saying that Robert would have to have the baby if that were the case.

We will just have to wait until the air date tomorrow, when the 'Twilight' themed show is broadcast, to see if those comments made the cut.

Winfrey's representatives have told USA TODAY that no such in-depth questioning took place. So the mystery of are they or aren't they looks set to continue.
