In promotion of her new album, 'Red,' Taylor Swift has been all over television this week, but she's so adorable in interviews that we really don't tire of her invading our living rooms. This morning on 'Ellen,' Swift stuck to her likeable interview posture, but blushed -- and had a bit of a freakout -- when the hilarious host prodded her about her ex-boyfriends.

It all started started when Ellen mentioned Swift's last appearance on her show with "boyfriend" Zac Efron. The 'Begin Again' singer insists that she and the actor are strictly platonic, and even performed a parody with him of Foster the People's 'Pumped Up Kicks,' where they poked fun at the host for always asking about her love life.

Since Swift refused to admit that she ever dated Efron (because she didn't date him), Ellen changed the subject to chat about 'Red.' At first, the 22-year-old super starlet thought she was going to get out of talking about boys, but the pushy host was a little too quick at the draw.

"Which song is about Zac on the CD?" Ellen quipped, which got a big laugh from the audience.

Swift started to look uncomfortable, but she barely had time to respond before she was asked who she is singing about in 'We Are Never, Ever, Ever, Ever, Ever Getting Back Together,' as Ellen likes to call it. The host then handed the country songbird a bell and showed a slideshow of pictures. She told Swift that when the subject of the song appeared in a photo, she could ring the bell and signal to the national audience who she has been singing about -- and which guys on the screen she has dated.

"I don't know if I'm going to do this--this is the one thing that I have. It's like the one shred of dignity that I have!" Swift answered. "People go and make guesses about it, and the only thing that I have is that one card!"

Hoping to compromise, Ellen said Swift could ring the bell for three different photos, and she could guess at the truth. Keeping the humor-level high, Ellen's slideshow revealed images of Swift with Efron, Danny DeVito, Justin Timberlake, Rob Lowe and a host of other men that the country singer hasn't dated.

Swift started to blush and buried her head in her hands, knowing she couldn't escape.

"Stop it! This makes me feel so bad about myself!" she said. "Every time I come here you put a different dude on the screen, and it really makes me question what I stand for as a human being. There's never been two guys on the screen two visits in a row. It's sad."

That joke really got Ellen laughing -- and the entire audience, too. In the end, the 'Red' hitmaker proved once again that she's a good sport.
