This morning Page Six is reporting that the woman in question is Courtney Crangi, jeweler Philip Crangi's sister and business partner. A "fashion insider" supposedly told Page Six, “After the breakup, Jenna fell in love with Courtney, whom she had been friends with for some time. They’ve known each other for years through the fashion business."
The two have been spotted at events and dinners together (which seems to be a bit of a stretch to prove a love affair), but the gossip column also reports that "friends say the new couple are quietly open about their relationship." And yes, we've also heard that they're together.
