Theirs was a whirlwind two-month romance that came to an end in December.
But Jake Gyllenhaal and Taylor Swift have sparked reports their relationship could be back on by dining together in Nashville this week.
The Love and Other Drugs actor and Taylor, 21, were spotted at Bound'ry – a restaurant near the country star's Nashville apartment – chatting by the fireplace.
"They did eat," a fellow customer told People magazine. "They were cordial to one another, but not affectionate."
Another source added: "There was no holding hands, but they seemed happy together."
Jake, 30, and Taylor were last spotted in public together on December 9.
On Sunday, the actor was accompanied to the Golden Globes by his ex-girlfriend, singer Jenny Lewis, but posed for red carpet photos on his own.
