Swift told DeGeneres she is 'always optimistic about love...always, sometimes,' in the episode, to be aired on Monday.
DeGeneres then joked: 'Especially if your boyfriend is Jake Gyllenhaal, because he is very handsome, y'all are just hanging out though right?'
The singer, who is on a promotional tour for her new Speak Now album, then acknowledged she did indeed spend the day with the 29-year-old actor.
She said: 'You have a picture of us on the [TV] screen, don't you?'
