Nicole Walker's pregnancy on "Days of Our Lives" will come with a huge paternity storyline, as she'll be unsure if her boyfriend EJ DiMera (Dan Feuerriegel) or her ex-husband Eric Brady (Greg Vaughan) is the father of her baby. Although Eric and Nicole are still obviously in love with each other, they have been divorced for quite some time. Nicole has moved on to a relationship with her another one of her ex-husbands, EJ — who fathered both of Nicole's lost pregnancies.

After Nicole and Eric were drugged, along with many others in Salem, they hallucinated and hit the sheets together, making it possible for either EJ or Eric to be the child's biological dad. Although Nicole has a long history with both men, Eric is the love of Nicole's life. Fans have wanted to see the couple get together and have a child for decades.

Now that Nicole is pregnant again, many viewers will be hoping that the character will not only have a healthy pregnancy, but that Eric will be revealed as the father of her child. Of course, the drama surrounding the paternity storyline will likely play out over the coming weeks, and viewers will have to wait to see how it all goes down.
