Tesla CEO Elon Musk’s ex-girlfriend, Jennifer Gwynne, is auctioning off photographs and personal items from their one-year relationship to raise money for her stepson's college tuition. Gwynne reportedly dated Musk in 1994, when they were in their 20s and were studying at the University of Pennsylvania. The items to be auctioned included their pictures, Musk's handwritten note and a necklace.
