A significant rumor about the upcoming season of One Tree Hill is making the rounds.

According to extras on set, Dan will have a pregnant girlfriend on season seven of the show.

Who will she be? Sources confirm that Brooke's nemesis Rachel  - returning actress Danneel Harris - will be the lucky lady to carry Dan's child.

Moreover, these same sources report that Harris was sporting a diamond engagement ring as well, leading to the assumption that Dan at least does the right thing once this news breaks.

Does this mean the character has a new heart? Or will he die and leave his child with either of his sons? Tune in for season seven.

Find out.
