London, Jan 15 (Agencies): Singer Taylor Swift was sad after her romance with actor Jake Gyllenhaal ended.

The country star, who dated Gyllenhaal, could not eat after she was dumped by the actor over telephone.

"She was not her usual bubbly, over-animated self. She didn't eat anything seemed very sad and definitely wasn't having a good time," said a source.

Meanwhile, another friend added that the phone call left the 21-year-old singer frustrated.

Reports have claimed that the nine year age-gap in their relationship left the 'Brokeback Mountain' star uncomfortable leading to an end to their brief romance.

"Jake reached out to her and started all of this, but now he's not acting as interested. He said he wasn't feeling it anymore and was uncomfortable with all the attention they got," another source said.
