Are they or aren't they?

On Friday's Ellen DeGeneres Show, Taylor Swift deftly fielded questions about Jake Gyllenhaal, with whom she spent some quality time in the NYC area last weekend.

When host Ellen DeGeneres asked the singer, 20, how she feels "about love right now," Swift replied, "I'm always optimistic about love...always, sometimes."

"But right now you are [optimistic]?" DeGeneres asked.

"Well, why wouldn't anyone be?" Swift answered.

"Especially if your boyfriend is Jake Gyllenhaal, because he is very handsome," DeGeneres teased. "Y'all are just hanging out though right?"

"You have a picture of us on the screen, don't you?" Swift retorted.

Swift and Gyllenaal, who is nearly a decade older at 29, were spotted Saturday touring the fall foliage and apple picking in Hopewell Junction, N.Y. "They looked happy," a witness said. The duo later attended an SNL taping and Sunday brunch in Brooklyn's Park Slope neighborhood.

During her Ellen appearance, Swift also talked about "Dear John," an angry ballad from her new album Speak Now, that seems to be about rumored fling John Mayer.

Swift told DeGeneres the track "could be" a "Dear John" about Mayer. "That song kind of is what it is," she quipped.

"OK, great," DeGeneres chirped. "We know the answer now. It's about him [John Mayer]. You didn't dispute it so obviously..."
