The girlfriend he loved in his early 20's, before he met Michelle reveals a very private side of a young Barack Obama.
Genevieve Cook was the 25-year-old daughter of a diplomat from Australia and she's speaking out for the first time in the new issue of Vanity Fair.
Obama was a student at Columbia University when he met Cook at a Christmas party in downtown Manhattan. She was drinking Bailey's Irish Cream from the bottle.
"I'm pretty sure we had dinner maybe the Wednesday after. I think maybe he cooked me dinner," Cook said. "Then we went and talked in his bedroom. And then I spent the night. It all felt very inevitable," she continued.
She said that on Sundays, Obama would lounge around bare-chested, dressed in a blue and white sarong while working on a New York Times crossword puzzle.
In his best-selling memoir, Dreams From My Father, Obama wrote about, "A woman in New York that I loved," but he never mentioned her by name.
The young Obama's girlfriend, Cook, lived on the top floor of a brownstone in the Park Slope section of Brooklyn. Obama actually moved in with her after graduating from Columbia. They liked to cook and Obama would jog every day in Prospect Park.
According to Vanity Fair, it was the "Deepest romantic relationship of his young life."
Crook wrote about her boyfriend in her diary: "The sexual warmth is definitely there-but the rest of it has sharp edges and I'm finding it all unsettling...Though he speaks sweet words and can be open and trusting, there is also that coolness-and I begin to have an inkling of some things about him that could get to me."
She also said that when she told young Obama that she loved him, he coolly replied, "Thank you."
INSIDE EDITION caught up with Good Morning America's Robin Roberts and asked her about the situation. Roberts replied, "If someone started looking at my relationships from my twenties...Ouch!"
Cook later married an Egyptian-born accountant and their wedding announcement appeared in The New York Times.
In her diary she predicted that Obama's wife was out there waiting for him. She said she would be, "a lithe, bubbly, strong black lady," that certainly fits the description of First Lady Michelle.
