In Ellen DeGeneres appearance to Taylor Swift concert, she acted like she just so happened to waltz on stage during the show, saying,

”I was looking for the ladies room. I am so sorry.”

It wasn't like Justin Bieber Punk'd Taylor Swift episode leaving T-Swift freaked out. But Ellen DeGeneres was different, the crowd was freaking out as the started appeared from the stage.

Compare to Justin Bieber's guesting, Ellen didn't do any rapping on Sunday night, the two did break into a touching rendition of Taylor’s “Our Song.”

Taylor played along, replying, “This has been happening quite a bit, people are just going about their daily lives and they end up on our stage. It happened a lot this week.” Taylor also made a surprise appearance of her own this past week.
