Nicole Richie is finally addressing the question everyone has been asking: Is she really pregnant?

“Yes I am. We are. I’m almost four months,” she tells ABC News’ Diane Sawyer in a new interview airing on Good Morning America Thursday and on 20/20 Friday.

Richie, 25, confirms that the baby’s father is rocker boyfriend Joel Madden, 28, whom she’s been dating since earlier this year.

Thank you Captain Obvious.
